CBA is signed, salary cap set

By Dan T. Rosenbaum

Apparently, in the wee hours this morning the league and union hammered out the final details of the new collective bargaining agreement. While I am still eager to find out what those details are, we have gotten word on what the salary cap, luxury tax threshold, and MLE will be.

2005-06

  • Salary cap: $49.5 million
  • Luxury tax threshold: $61.7 million
  • MLE: 5.0 million

2006-07 Estimates

  • Salary cap: $49.2 million
  • Luxury tax threshold: $59.7 million
  • MLE: $5.4 million

Except for the fact that 49.5% apparently was used to compute the salary cap (rather than 51% like will reportedly be used next season), the salary cap and luxury tax threshold are almost dead on what I predicted. This suggests that the formula for projected BRI was not changed substantially, which would mean that we should expect the salary cap to stay about the same in 2006-07 and for the luxury tax threshold to fall.

Now the MLE is a bit lower than I expected, so it appears that perhaps some changes were made to that formula. I am eager to see what they are.

The Hornets franchise is a danger to the league

By Dan T. Rosenbaum

ESPN.com is reporting this AP story.

NEW ORLEANS -- A new lawsuit filed against the New Orleans Hornets claims the team deprived sales personnel of commissions by falsely recording sales of private suites as if they were group ticket sales in less expensive sections -- a practice that also could have resulted in inflated attendance figures.

The lawsuit is one of several new actions filed this week against the Hornets, who already were accused of failing to pay overtime in a federal lawsuit filed earlier this year. There are 12 plaintiffs in that first case, one of whom still works for the team.

The new legal actions include a request for a protective order, filed in response to allegations in sworn affidavits, that Hornets executives have sought to intimidate other employees who might qualify to join the federal overtime lawsuit by threatening firings and bad references, which would be illegal. The request also alleges that certain executives have made false statements about the lawsuit in an effort to discourage employees from participating.

I hope the league takes these allegations very seriously. I love the NBA and hate to see a franchise do so much damage to the NBA. The Hornets franchise has already poisoned the well in Charlotte, which has made it all the more difficult for the new Bobcats franchise to get traction there. Now it appears to be doing the same thing in New Orleans.

The league is very concerned with its image and thus has in the past dealt very harshly with criticism of referees by Mark Cuban and Jeff Van Gundy and transgressions by players, such as Ron Artest. The Hornets are damaging the NBA image much more than Cuban, Van Gundy, or Artest ever did, and so I would think it would be in the league's best interest to deal with them as swiftly and sternly as is possible under its rules.

David Stern has a tremendous amount of political capital in the league. I think it would be another testament to him if he could creatively come up with a way to help the league do something about this Hornets' franchise.

Update: I intend this to in no way be a criticism of the basketball people for the Hornets. They have, in general, tried to do a good job under very trying circumstances.

Defense for the big men: what do the adjusted plus/minus ratings say?

By Dan T. Rosenbaum

If I had a dime for every time I heard that you can't measure defense with stats, I would be a rich man. (Well maybe not rich, but I might have enough money for a nice dinner.)

Steals, blocks, and defensive rebounds - they give us only a snapshot of what a player does on defense. We would like to have more and better data to measure defense. One direction is to collect better defensive statistics, an effort that is being spearheaded by Roland Beech at 82games.com.

Another approach is to use plus/minus statistics to measure how a team defends when a player is in the game versus when he is not. It would seem odd to say that a player was a good defender when his team defended better when he was on the bench than when he was in the game.

Now, of course, it is important to account for who a player is playing with and against. Playing beside Ben Wallace might even make me appear to be a good defender. For that reason I compute adjusted plus/minus ratings that account for who a player is playing with and against. These adjusted plus/minus ratings can then be broken down into their offensive and defensive components.

In "Measuring How NBA Players Help their Teams Win" I describe the gory details of how I compute these adjusted plus/minus ratings. (I have made a few changes since then, along with adding another year of data.) It takes a lot of data for adjusted plus/minus ratings to tell us anything useful and for that reason it is useful to ask another question. What is the average adjusted plus/minus rating of players similar to a given player? Answering this question can give me a second estimate of a players' defensive productivity and help combat errors from adjusted plus/minus ratings due to lack of data.

So combining ratings of defense from a players' own adjusted plus/minus rating and that of players similar to him, which players are the best defenders? I list the best and worst by position among players playing 1,000 or more minutes in 2004-05. These ratings are predictions for the 2005-06 season assuming that younger players will improve their defense and older players may see a decline in their defense.

Top Five Centers:

  1. Ben Wallace
  2. Dikembe Mutumbo
  3. Theo Ratliff
  4. Jason Collins
  5. Joel Pryzbilla

Bottom Five Centers:

  1. Primoz Brezec
  2. Marc Jackson
  3. Predrag Drobnjak
  4. Mark Blount
  5. Eddy Curry

Ben Wallace by all accounts is a game changer as a defender, so it is comforting to see him at the top of this list. Wallace is joined by three of the top shot blockers in the league in Dikembe Mutumbo, Theo Ratliff, and Joel Pryzbilla. Jason Collins has consistently over the past three seasons had an above average adjusted plus/minus rating and the reason is because he is a very solid defender.

Primoz Brezec was a solid offensive player for Charlotte last season, but his poor defense resulted in the Bobcats playing worse when he was out on the court. Eddy Curry also has consistently had a below average adjusted plus/minus rating over the past three seasons, and the biggest reason is his poor defensive play.

Interestingly, Kurt Thomas who was recently acquired by the Phoenix Suns rates in the bottom third among centers in defense. It is rather surprising to hear analysts argue that a players who made the 5th worst defense (the Knicks) worse is going to help the 17th best defense (the Suns) get better.

Top Seven Power Forwards:

  1. Tim Duncan
  2. Kevin Garnett
  3. Nick Collison
  4. Tyson Chandler
  5. Nenê
  6. Andrei Kirilenko
  7. Rasheed Wallace

Bottom Seven Power Forwards:

  1. Matt Bonner
  2. Cliff Robinson
  3. Antawn Jamison
  4. Juwan Howard
  5. Austin Croshere
  6. Antoine Walker
  7. Shareef Abdur-Rahim

I am sure no one will be surprised to see Tim Duncan and Kevin Garnett at the top of the list on defense for power forwards. Nick Collison is a bit of a surprise to anyone who did not watch the Sonics play a lot. (Please note that with just one year of data, ratings for rookies like Collison are more prone to error.)

I am sure many will be surprised to see Cliff Robinson in the list of worst defensive power forwards, but last season he had a dreadful adjusted plus/minus rating. Both Golden State and New Jersey played better defense when he was on the bench.

It is time for bed now, so I will leave the other positions for the next installment. But as a sneak preview, there will be a player who is about to receive a maximum salary offer who will rate as the worst defensive player at his position. Can you guess who that might be?

For more comments about this methodology and these results from some of the top basketball statistics experts, as well as lots of other interesting discussions about basketball statistics, see the APBRmetrics message board.

Kudos to Chad Ford at ESPN.com

By Dan T. Rosenbaum

Update: I am pushing this up, because it has been reported that Chad Ford is leaving ESPN. The abuse that I am seeing him get today is extremely immature, largely a combination of jealousy and ignorance.

Around this time of year with all of the rumors flying about, sportswriters like Chad Ford take a lot of abuse. But in my humble opinion, Chad Ford is one of the best sportswriters out there. I don't think anyone works harder than he does. He travels all over the country - all over the world - for his stories. I have seen him working and he is constantly talking to people, either in person or on the phone. He understands the collective bargaining agreement as well as any sportswriter (and a lot of front office personnel), and he has started to include advanced statistics from 82games.com and John Hollinger in his articles. And he has a law degree, to boot.

I think we all underappeciate how difficult it would be to be in his shoes - to let the public know what he knows without overstepping. I think he does a very good job at that. In my humble opinion, I think we should thank our lucky stars that it is Chad Ford (and not someone else) that is in the "insider" position at ESPN.com.

P.S. I like Marc Stein a lot too, but it is Chad Ford who gets most of the abuse on message boards at this time of the year.

Part II: Some ideas about the use of capologists and stats experts in NBA front offices

By Dan T. Rosenbaum

A key issue not addressed in Part I of this series is why teams don't invest more in capologists and stats experts.

For the most part, I think teams have come to peace with the importance of capologists and over the years understanding of the salary cap and luxury tax has increased significantly league-wide. I think teams would be better off with more intergration of the salary cap and basketball expertise, but teams are not doing too badly in this area. That bodes well for stats experts eventually finding a place in NBA front offices.

But for now it is another story. There are teams that have integrated statistical expertise in a serious, meaningful way, but for the majority of teams serious statistical analysis is treated like an ugly stepchild. It is hidden deep in the bowels of the organization and let out occasionally to do some chores.

I think the biggest roadblock to stats experts is the idea that stats experts are a substitute for basketball people rather than a complement. That mindset is probably an artifact of the Moneyball revolution in baseball where arrogance, condescension, and mistrust have often characterized the relationship between baseball and stats people. On the basketball side, we certainly have had some of the same problems, but I think many of the key ambassadors from the stats side have a lot of respect for what basketball people know about the game and how critical that is in understanding the stats. Likewise, there are a great number of basketball people who respect what stats experts do.

However, because of the interactions between players and importance of roles, statistical evidence is unlikely to be as clear-cut in basketball as it is baseball. With arguments that are more subtle and evidence that is more tenuous, it is difficult for stats experts to be convincing to a skeptical audience of basketball people with a limited understanding of the nature of statistical evidence.

Complicating this delicate interplay, some stats experts have made grandiose claims about their methodologies. These may be good marketing strategies, but when these grandiose claims (often made without any acknowledgment of the uncertainty in all statistical evidence) turn out to be false, it damages the credibility of the entire stats community. It is not the mistakes that rub basketball people the wrong way (everyone makes mistakes), it the air of superiority with which these claims are made. Basketball people have paid their dues and learned the game through countless hours playing and watching basketball, and so it has to be grating to hear someone tell them that their computer program makes them obsolete. Especially when that computer program starts spitting out absurd results that are obviously wrong.

This makes it hard for basketball people to see the value of serious stats work, especially when they repeatedly get free offers from academics or retired millionaires from Microsoft to do work for them for free. In such an environment all stats people look the same, so it seems ludicrous to invest time and money into any one expert. But as I argued in
Part I, it is that kind of investment that will result in stats experts helping teams.

But this should not all be put on the teams. We in the basketball stats community need to do a better job communicating. We need to come up with convincing arguments for why we are relevant, why we are not a threat to basketball people, and how we can help basketball people be better at what they do. It will take time, but eventually I think we can do this.

Salary cap percentage will only rise to 49.5% in 2005-06

By Dan T. Rosenbaum

In an e-mail Chad Ford of ESPN.com told me that the salary cap percentage will not be 51% in 2005-06. It will be 49.5% in 2005-06 and 51% starting in 2006-07. This means that if the formula for the salary cap does not otherwise change, the salary cap is likely to be between $49 and $50 million. If the formulas do change (and they should), the salary cap could be quite a bit less than $49 million.

The teams most affected by this phasing in of the salary cap percentage probably are Cleveland and Milwaukee. Both teams are bumping up against the salary cap, so it may be tough for Cleveland to be competitive for Marko Jaric or possibly for Milwaukee to be able to re-sign Za Za Pachulia.

Also, since maximum salaries are a function of the salary cap, maximum salary players, such as Michael Redd and Joe Johnson, are likely to be paid a little less than they would have if the salary cap percentage had not been phased in.

The Moratorium Continues

By Dan T. Rosenbaum

ESPN.com is reporting that the moratorium will not end on July 22nd because negotiations for the new collective bargaining agreement are ongoing. A tentative agreement was passed on June 21, so this will push the post-agreement negotiations past a month. During the negotiations for the 1999 CBA a tentative agreement was in place on January 6 and the moratorium ended on January 21 - a span of 15 days.

Now, of course, there was a lot more pressure to resolve issues last time when games were being lost, but this suggests that these negotiations are more than a mere formality. It will be interesting to see the outcome.

A suggestion for changes in how the salary cap and MLE are computed

By Dan T. Rosenbaum

In "What will the salary cap, luxury tax threshold, and mid-level exception be in 05-06 and 06-07?", I said that significant changes to the collective bargaining agreement would result in big changes in my estimates of the salary cap, luxury tax threshold, and mid-level exception. (Folks posting my estimates generally have ignored that admonition.) But in this piece I would like to lay out how I think the formulas should be changed and how that might affect these estimates.

First of all, let's review the technical details about salary cap formula.

Salary Cap:

Salary cap = [Projected BRI * 0.51 - (29/30) * Projected Benefits]/29, where

  • 29 is the number of non-expansion teams in their first two seasons (equals 30 in 2006-07).
  • 51 percent is the salary cap percentage that was increased from 48.04 percent in the previous CBA.
  • I am using $114 million and $120 million for Projected Benefits in 2005-06 and 2006-07, respectively.
  • Projected BRI = Estimated National TV BRI + 1.08 * Previous Season Non-National TV BRI - Previous Season BRI Shortfall.
  • Previous Season BRI Shortfall = Previous Season BRI - Previous Season Projected BRI. (This shortfall is never less than zero.)

Because of a $37 million lump sum payment from Fox Sports to the Los Angeles Lakers that will result in a bump up of BRI of about $64 to $74 million, BRI will almost surely exceed Projected BRI in 2004-05. Thus, the Previous Season BRI Shortfall is likely to be zero in the 2005-06 salary cap calculations. However, because that lump sum payment will not reoccur in 2005-06, the Previous Season BRI Shortfall is likely to be substantial in the 2006-07 salary cap calculations. And that is likely to result in the salary cap falling in 2006-07. (It will also fall because the number of non-expansion teams will increase to 30.)

This adjustment for previous shortfalls is what causes the lumpiness in the year-to-year salary cap calculations. Every other year there is a shortfall and this results in small increases (or decreases) in the salary cap followed by huge jumps in the next year. My suggestion to fix this jumpiness is the following.

  1. Instead of the 1.08 multiplier on Previous Season Non-National TV BRI, the league should use the average growth rate of Non-National TV BRI over the previous three seasons.
  2. The league should do away with any adjustment for previous shortfalls. If an adjustment is absolutely necessary, I would suggest that it be averaged over three years and only be based upon National TV BRI.
  3. The league should go back and spread the $37 million lump sum payment (from Fox Sports to the Lakers) over the life of that contract. If I had my way, I would even allow this change to affect the calculation of 2004-05 BRI, except for in calculations for whether or not the luxury tax is triggered. (Teams had planned on no luxury tax partially because of this lump sum payment.)

The first two suggested changes are not that important in and of themselves. Alone they project the salary cap to $50.8 million in 2005-06 and $49.90 million in 2006-07. (This is relative to $51.0 and $49.4 million.)

But the third suggestion is very important. This projects the salary cap to $49.2 million in 2005-06 and $49.9 million in 2006-07.

Luxury Tax Threshold:

The luxury tax threshold formula, if it is now based upon projected BRI, is the same as the salary cap formula, except that 0.51 is replaced with 0.6111. Under the three suggestions for changes above, the luxury tax threshold would be $59.8 million in 2005-06 and $60.6 million in 2006-07 (versus $61.9 million in 2005-06 and $59.9 million in 2006-07).

Mid-Level Exception:

Mid-Level Exception = 1.08 * [Previous Season's League-Wide Salaries/(12.5 * 29)]

  • League-Wide Salaries do not include expansion teams in their first two seasons.
  • 29 is the number of non-expansion teams during their first two seasons.
  • Only injured players whose salaries do not count for salary cap or luxury tax purposes are not counted in Previous Season's League-Wide Salaries.
My suggestion is the following.

  1. Instead of the 1.08 multiplier, my suggestion is to use the average growth rate of BRI over the past three seasons (use only first two seasons in 2005-06 so as not to use BRI numbers from previous TV contract).
  2. Instead of assume 12.5 players per team, I suggest assuming 14.
  3. I suggest including all salaries, including those of injured players removed from team salary.

These changes would result in a smaller MLE of about $4.6 million in 2005-06 and $4.9 million in 2006-07.

I do not know if these formulas are up for debate in the drafting of the new collective bargaining agreement, but these are the result of my suggestions for potential changes.

Salary cap, luxury tax threshold, and mid-level expection using my suggestions for potential changes (earlier projections in parentheses)

2005-06

  • Salary Cap - $49.2 million ($51.0 million)
  • Luxury Tax Threshold - $59.8 million ($61.9 million)
  • Mid-Level Exception - $4.6 million ($5.2 million)

2006-07

  • Salary Cap - $49.9 million ($49.4 million)
  • Luxury Tax Threshold - $60.6 million ($59.9 million)
  • Mid-Level Exception - $4.9 million ($5.6 million)

Updated thoughts on the CBA

By Dan T. Rosenbaum

More and more of the details of the CBA are dribbling out daily. In "How will the new NBA collective bargaining agreement and new luxury tax rules affect the free agent market?", I have included various updates. The Gilbert Arenas provision is updated, and due to conflicting reports about the distribution of the luxury taxes, I have significantly changed my assessment of this deal. I think that until we know how the luxury taxes are distributed, it is an open question how the free agent market will be affected over the life of this deal.

It fascinates me that there is uncertainty at this point about how the luxury taxes might be distributed. This issue is more important to the decision-making of teams than all but a handful of other changes to the CBA, yet it appears possible that many (if not all) teams do not know how these taxes will be distributed. What this means is that teams may not know how much free agents will cost them and for some reason are not banging down the doors of the league to find out. I talk more about this issue in
"How will the new NBA collective bargaining agreement and new luxury tax rules affect the free agent market?".

Some ideas about the use of capologists and stats experts in NBA front offices

By Dan T. Rosenbaum

I would like to start out with a big disclaimer. I have never worked for an NBA team in any way whatsoever, so you should take what I say with a big grain of salt. But I have talked to a lot of people in a lot of NBA front offices, and I think I might have some useful ideas (and surely some bad ideas) about how to best utilize capologists and stats experts. With teams paying skyrocketing costs for coaches, I figured that some brainstorming about other front office personnel might be interesting.

How teams use capologists

Most teams have a capologist and a stats expert (usually separate people). The capologist often is a lawyer or accountant outside of the basketball operations department - sometimes even outside the organization. Their capologist duties often are only a small part of their overall responsibilities, so they concentrate on learning the complex rules governing trades, free agency, and the luxury tax. This leaves precious little time to think strategically about how to use these complex rules to benefit their team through trades, structuring free agent deals, etc. Also, putting together forecasts of future salary caps, luxury taxes, and league-wide free agent activity is not generally done in any systematic manner. And perhaps most importantly, by not being a "basketball person," a capologist often is seen as a resource for asking questions and not as an integral decision-maker.

But there is a tremendous amount of heterogeneity across teams, so it is a big mistake to overgeneralize. The lawyer/accountant model of a capologist described above is not the only model. Other teams invest salary cap expertise into their basketball operations people. The Chicago Bulls and San Antonio Spurs are two of the most successful models for these two different models of capologists.

Take, for example, a trade made in October 2002 that was way under the radar screen. San Antonio traded Erick Barkley to Chicago for cash considerations and Chicago immediately waived Barkley. What was the purpose of this trade?

San Antonio probably forecast that their team salary would be above the luxury tax threshold (and below the cliff threshold). So Barkley's salary would have cost the Spurs $765,600 in salary, $765,600 in luxury taxes, and about $2.4 million in lost luxury and escrow tax distributions. Even if they paid Barkley's full salary and included a small bribe in their deal with the Bulls, they could have saved more than $3 million in a move that did not affect their basketball team one iota. Three million dollars likely would pay the salary and overhead for a capologist for more than a decade.

And it is no coincidence that San Antonio and Chicago pulled off this deal. Chicago has lawyer Irwin Mandel who is reported to be one of the best salary cap experts in the league. Mandel is not a basketball person but he has been with the Bulls forever, and almost plays the role a President would play on other teams. When general manager John Paxson meets with agents, it is not uncommon for Mandel to be with him during negotiations.

San Antonio has Sam Presti, whom general manager R.C. Buford has called "one of the talented young minds in the game." Presti is a rarity in the business being a capologist and stats expert. Also, general manager R.C. Buford reportedly is one of the best salary cap experts in his own right.

While Chicago represents perhaps the best application of the non-basketball person model of capologist, San Antonio employs what I believe is a better model. They have invested salary cap expertise into their key basketball people, in essence creating a culture that is probing for arbitrage opportunities based upon the salary cap. And that, I believe, is one of the reasons why San Antonio is one of the best-run franchises in the NBA. Because their key basketball people have a solid understanding of the nuances of the salary cap, they see opportunities that are missed by teams that departmentalize basketball and salary cap expertise.

Another example is the trade that brough them Hedo Turkoglu and Ron Mercer two years ago. They served as broker for a trade between Indiana and Sacramento, and in return got a couple serviceable players that did not cost them any salary cap space in the next summer when they were looking to sign Brent Barry and re-sign Manu Ginobili. Such a move may not seem like much, but little moves like than can be what separates the championship teams from everyone else.

How teams use stats experts (and my philosophy on basketball stats experts)

The stats expert often is a young person who may have worked his way up in the organization, often starting out working in the video department. Typically he has very little formal statistical training, but learns about basketball stats through reading and talking with other experts.

Another common approach is to hire a statistician (or two) with some advanced training, either in-house or as an outside consultant. Often these statisticians may technically be quite proficient; they may produce advanced statistics with dizzying levels of math. But do they have the basketball knowledge needed to ground their analyses? Sometimes, but not always.

And therein lies the problem. We all use statistics. Even the oldest of the "old school" basketball people look at box scores and per game statistics. Stats experts have value not because they are the only ones looking at stats. Their value comes from having good judgment about stats - good judgment that comes from a solid understanding of both basketball and statistical analysis more generally.

But the bar for this good judgment is set very high. Basketball is not like baseball, where the repeated one-on-one contests between batters and pitchers and relative lack of interaction between teammates generates loads of data that can be usefully analyzed with the statistical tools taught in a good undergraduate statistics class.

In basketball, the centrality of teammwork and interactions between players requires that we need to account for a player's roles, as well as the players he plays with and against. Doing so requires a lot more creativity and more sophisticated tools than what are used by baseball analysts. An Ivy League graduate who is handy with Excel is not going to be as useful in basketball as they have been in the Moneyball world of baseball. It is not enough to be smart with numbers.

That is why I think the folks who end up doing stats in a serious way for basketball teams are going to have more formal training (or at least more extensive experience working with basketball stats) than the folks in baseball. The problem is harder in basketball, so the analysts are going to need a bigger toolbox they can work with.

(As I see with the graduate students I teach, the demand for skills working with complex data are growing exponentially in the job market.)

But a good practical understanding of statistical analysis is not enough. The centrality of teamwork and role players significantly increases the basketball knowledge a stats expert must have in order to make good judgments. This again makes basketball very different from baseball, where a lot can be learned sitting in an office and churning out numbers. Not so in basketball, where context matters.

So the teams that get this right are going to need two things - a person with solid training in (or extensive practical experience with) statistics/econometrics and a solid understanding of basketball.

The gold standard of stats experts - Dean Oliver - is no accident. Oliver who worked for the Sonics this past season is a rarity among stats experts. He is Ph.D. (in environmental engineering, I think) who has worked as a scout. He combines formal training, a solid understanding of basketball, and lots of experience (he has been at this for more than a decade).

Oliver, I believe, played a subtle but significant role in the Sonics' remarkable turnaround this season. Conventional wisdom gives McMillan almost all of the credit, but Mike Kahn of FoxSports.com in a piece that is highly supportive of McMillan writes that McMillan "contemplated resigning," after management said "they expected to be in the 2005 playoffs." Kahn goes through a litany of reasons why McMillan supposedly was unhappy with this team, so one has wonder how in this atmosphere McMillan transformed from a mediocre coach to a great one.

Oliver certainly was not responsible for the distinct style the Sonics played with this season - a style that did a masterful job of exploiting the talents of its very good role players. But I think his numbers helped the whole staff have more confidence in this unorthodox approach. Oliver, like a lot of the players on the Sonics, was by no means a superstar with all of the answers; this was no Moneyball repeat. But he played a role and played it well. And if a stats expert can do that, he is earning his way.

That ideally is how a team uses a stats expert. Not to run a team as in the Moneyball world of baseball. But as a role player who works hard to become a good basketball person and makes all of the basketball people around him better at what they do. As a role player who can help make sense of advanced methodologies and concepts in basketball statistics. More importantly, as a role player who can help put data in the right perspective and understand when to pay attention to the data and when to ignore it.

This final point is greatly underappreciated. If there is anything my experience teaching and working with stats has taught me is that non-stats experts spend ungodly amounts of time looking at stats that are more misleading than useful. (Although highly trained "experts" can be worse if they don't understand basketball very well. Or if they just do not have good intuition for data.) I just cringe when I hear of teams using plus/minus data in ways that are almost surely more distracting than helpful.

At the end of the day, using stats wisely is about making good judgments. And it seems quite a risk when teams rely so heavily on stats "experts" with very little statistical training (or experience) and/or limited basketball knowledge.

[I will add more to this later in Part II.]

How will the new NBA collective bargaining agreement and new luxury tax rules affect the free agent market?

By Dan T. Rosenbaum

The league and the union are still hammering out details on their new collective bargaining agreement (CBA), but heading into crunch time, it appears that the league is making a game of it. The league got concessions on a handful of non-economic issues, but the economic issues tended to fall in the players' favor. This new deal removes some of the teeth from the luxury tax (how much is still an open question), but guarantees a luxury tax in every season and at a lower threshold than in this past season. The salary cap increase likely will more than offset the changes in maximum contract lengths and raises.

Overall, I am now uncertain how to assess this deal. If the luxury taxes are evenly distributed to all 30 teams, then this was a big win for the players who will likely receive more than 60 percent of basketball-related income (BRI) over the life of this agreement - an outcome that will put a lot of pressure on owners during the next round of negotiations.

If the luxury taxes are distributed in some other way, then I think this it is very possible that this deal was pretty fair for both owners and players.

First, let me lay out the major provisions of this new deal. (I borrow heavily from David Lord at DallasBasketball.com here.) The provisions in green should significantly increase the overall compensation of the players, while those in red should decrease them.

  1. The luxury tax will stay as is - dollar-for-dollar on teams above the 61.1% of BRI threshold used prior to 2004-05, except that the new deal guarantees that the luxury tax will be triggered in every season of the deal. [Note that this season the threshold was at 63.3% of BRI.]
  2. All teams (including those who pay tax) under the new deal will receive a full share of the escrow tax collections. I have seen conflicting reports of what will happen with luxury tax collections. [In the old deal, they received amounts that were reduced or eliminated entirely, according to their spending level.]
  3. Luxury Tax Amnestry Provision (Allan Houston Rule): This summer, teams will be given a one-time opportunity to waive one player and eliminate the luxury tax on any future contractual payments to that player. The salary will still count towards the salary cap, and payment will still have to be paid to the player according to the contract, but the team will not be subject to tax on that player’s contract. [Speculation is that this luxury tax amnestry provision will also apply to previously waived players, but not players traded for after June 1st.]
  4. Luxury tax exceptions will be added in some as-yet-undisclosed fashion for minimum salary players.
  5. The salary cap and luxury tax exceptions for players who are deemed ‘permanently injured’ will begin after one year rather than two.
  6. The escrow tax on player salaries will be reduced from 10% in year one, to 9% in years two through five, and to 8% in year six of the agreement.
  7. The players will be guaranteed a total of 57% of BRI each year, up from no guarantee. [I believe this guarantee increases in some as-yet-undisclosed fashion as overall league revenues increase.]
  8. The escrow tax will only be retained by the owners to offset salary costs when total salaries exceed 57%, just like in the last season of the prior deal, but in the new deal that threshold will be raised if overall league revenues increase in some as-yet-undisclosed fashion.
  9. The salary cap will be set at 49.5% iof Basketball Related Income (BRI) in 2005-06 and 51% thereafter, up from 48.04%. That means last year's salary cap of $43.87 million will likely go up to the $49 to $50 million range this summer, once revenue increases are factored into the equation. [Presumably, maximum salaries will increase, since they are tied to the salary cap.]
  10. Gilbert Arenas Provision: Restricted free agents in their first two seasons can be offered contracts above the MLE by teams with salary cap room, but in the first two seasons of such deals players will be paid the MLE. After the second year of the contract, the contract can increase to the maximum allowable salary for that player. This provision allows a player's original team to match any offer and retain him as long as they have their MLE available. Example: Suppose Chris Duhon is offered a contract of $10 million, $10.8 million, and $11.6 million in years 1, 2, and 3. He would be paid the MLE in the first two seasons and $11.6 million in year 3. But only a team with $10 million in salary cap space could offer such a contract. [Presumably, the cap holds in the first two seasons of such contracts are $10 million and $10.8 million and not the MLE. It is unclear how the luxury tax would apply to such contracts.]
  11. A team will have 7 days to match an offer for a restricted free agent (down from 14).
  12. The maximum length of a new contract will now be 6 years for a player who signs with his current team (down from 7), and 5 years for a player who signs with another team (down from 6).
  13. The maximum annual raises on a new contract will now be 10.5% of the first-year salary (not compounded) for a player who signs with his current team (down from 12.5%), and 8% for a player who signs with another team (down from 10%).
  14. First-round picks will be given standard contracts with two years guaranteed (down from 3), followed by two years of team options (up from 1). The contract amounts will remain standardized. [Presumably, the option for year 3 would have to be picked up prior to year 2. This is very early to give up on a rookie, so it is likely that teams would decline this option very rarely.]
  15. There are no changes being made to the general salary cap exception mechanisms which allow teams to exceed the salary cap to add players, such as the Bird Exception, Million Dollar Exception, Mid-Level Exception, etc. [I presume there could be changes to the formulas used to compute these exceptions.]
  16. For teams over the salary cap, trades will be allowed as long as they trade away as much first-year salary as they receive within 25% (up from 15%) + $100,000.
  17. Base-year compensation (BYC) rules, for trades involving players who just received a sizable raise, will be relaxed in some as-yet-undisclosed fashion. [I have heard that BYC status will end at the end of the moratorium the following season rather than a full calendear year later.)
  18. Minimum salary levels will be increased by 3.5%.
  19. Teams will be required to have an average of 14 players (up from 11) under contract. [I have heard teams will be required to have 13 players with an unknown maximum. I am not sure what mechanism there will be to guarantee an average of 14 players.]
  20. The active roster will still be limited to 12 players, but the designation for the others will now be ‘inactive’ rather than ‘injured.’
  21. The NBA age limit will be 19, and one year past high school for Americans, based on calendar year. [There is likely to be a related league rule implemented that prohibits NBA scouts and personnel from scouting any high school games.]
  22. The NBA Developmental League (NBDL) age limit will be 18, down from 20.
  23. Teams will be able to send players with less than two years experience to the NBDL for needed development during the year, while still retaining full rights, with the ability to recall any such player at any time as desired. Such players will receive their full NBA pay.
  24. Teams will be able to send an assistant coach to their associated NBDL team to work with and monitor the development of their players.
  25. Players will be subject to as many as 4 random drug tests per year (up from 1), with penalties increasing for failing a test on a 4-strike system (5-10 games, 25 games, 1 year, lifetime).
  26. Suspensions for on-court misbehavior will be subject to arbitration if the penalty exceeds 12 games (formerly there was no arbitration regardless of length).
  27. There will be a longer-than-usual July moratorium this summer, as the wording on the deal is hashed out, but summer leagues and negotiations with free agents will be allowed to take place during that time without interruption. No new contract signings (except for draft picks) can take place until the moratorium ends this summer.
  28. More money will be added to pension payments for the older retired players, pending approval under IRS regulations.
  29. New rules begin with the new season that starts July 1, 2005.

On the economic issues, the league was able to reduce the lengths of guaranteed contracts and the size of maximum raises, which they believe will rein in costs. But I think rather than reducing costs, these changes will simply redistribute compensation from unproductive to productive players. That is a good thing for both sides (and for fans). Moreover, for maximum salary players these changes in guaranteed contracts were largely mitigated by the increase in the salary cap, which increases maximum salaries. In addition, the increase in the salary cap will increase the number of teams able to offer large contracts, which will push up salaries for all players. All in all, I think this set of changes will increase the share of revenue going to the players, but not by much.

It is the luxury tax (and salary cap) provisions that will most affect league-wide player salaries. The league did get a lower threshold for the luxury tax - the 61.1 percent of BRI threshold used in 2001-02 through 2003-04, which is down from the 63.3 percent used in 2004-05. Also, the new deal guarantees a luxury tax in every season. Altogether this lower luxury tax threshold and certainty of the luxury tax being triggered should help control spending.

That said, the big enchilada in this deal is the change in how luxury and escrow taxes are distributed back to the teams. In the old deal the bulk of the $300 million or so a year (in luxury and escrow taxes) went to teams below the luxury tax threshold. This resulted in the first $3 to $4 million spent above the luxury tax threshold costing teams $3 to $4 million in luxury taxes and $8 to $10 million in lost distributions. That, in effect, was a 300 to 400 percent effective tax rate for spending just above the luxury tax threshold. That got teams attention and for some teams made the luxury tax threshold a "hard cap."

In the new deal, escrow taxes reportedly will be distributed evenly to all 30 teams. It is uncertain how luxury taxes will be distributed. Under an even distribution of luxury taxes to all 30 teams, the effective tax rate would only be 100 percent for spending just above the luxury tax threshold. This lower effective tax rate would result in more teams blowing past the luxury tax threshold when they believe that an extra player or two significantly increases their chances of success.

Under a distribution tilted towards teams below the luxury tax threshold, we may see the return of effective tax rates above 100 percent. They almost surely will not reach the 300 to 400 percent effective tax rates in the old deal, but even a 200 percent tax may be enough to rein in spending for many teams. It is possible that the league also could reduce distributions only for teams spending well above the luxury tax threshold. This would, in effect, be a back-door "super tax."

Added to this, the luxury tax amnesty provision and luxury tax exceptions for injured players and minimum salary players will reduce the exposure of high-spending teams to the luxury tax. By being able to shield tens of millions of salary from the luxury tax, these teams will feel more free to spend on new players. Also, the players waived under the luxury tax amnesty provision will result in additional "good" players in the free agent market. This also will increase the demand for teams to spend more.

Together these provisions along with an even distribution of the luxury taxes would remove the teeth from the luxury tax, resulting in more teams being willing to pay a little luxury tax and in high-spending teams feeling more free to be aggressive in their free agent and trading activity. (The relaxation of trading rules also will help aggressive teams in this regard.)

But again, a lot of this hinges on how the luxury taxes are distributed. The luxury tax tiger may not have lost all of its teeth.

And as mentioned above, the salary cap will increase significantly, which will result in more teams below the salary cap and teams below the salary cap having more money to spend. If the luxury taxes are distributed evenly, the luxury tax changes will result in middle- and high-spending teams being more aggressive in the free agent market, while the salary cap increase will result in lower-spending teams being more aggressive.

All told, if luxury taxes are distributed evenly to all 30 teams, these changes should result in players' salaries rising signficantly. (And this ignores the reduction in escrow tax over the life of the deal.) Counting all salaries (including those for injured players that do not count towards the salary cap), here is the share of BRI that players received the last few seasons and my predictions for 2004-05 through 2006-07.

Players' Share of BRI (After Escrow Tax is Paid) Under Even Distribution of Luxury Taxes

  • 2002-03: 60.1%
  • 2003-04: 59.3%
  • 2004-05: 58.1%
  • 2005-06: 61.7%
  • 2006-07: 60.3%

As you can see, the players' share of BRI had been declining under the old deal as teams "got religion" about the luxury tax. But if luxury taxes are distributed evenly, my prediction is that the new deal will undo much of the spending restraint of the old deal, resulting in the players' share of BRI rising above 60 percent. That will put pressure on owners to drop that percentage in the next round of CBA negotations, six years from now.

If luxury taxes are not distributed evenly, then the effect on the free agent market and players' share of BRI would depend heavily on how they distributed the taxes. But my guess is that under this scenario, the players' share of BRI would be much less likely to rise above 60 percent.

But that leads to an obvious question. If the luxury taxes being distrubted evenly would so result in the deal lopsidedly favoring the players, why would the owners sign off on this deal?

Well, first of all, I don't know if the owners have formally signed off on this deal and Chad Ford of ESPN.com has reported that negotiations over details to the new deal is going "slower than expected." That said, I have heard nothing to indicate that the deal could unravel.

Second, as I have discussed in the NY Times and in my luxury tax piece, the luxury tax under the old deal likely caused a lot of dissension among low- and high-spending owners. That dissension may have eroded David Stern's bargaining position. I would not be surprised if the union reached out to high-spending owners during this negotiation process, since if the luxury taxes are distributed evenly, high-spending owners were big winners in this deal.

In addition, because of the loss of revenue in the 1998-99 lockout, the players' share of revenue skyrocketed to around 65 percent during the first few years of that deal. The owners may have been apprehensive about a repeat of that worst case scenario. In contrast, fewer than half of the NBA players were around for the last lockout so the repurcussions of a lockout may not have scared them as much.

All of this leads to a second question. How come we do not know how the luxury taxes will be distributed, especially since this seems to be such a critical issue?

I am bewildered by this. How luxury (and escrow) taxes are distributed is critical to the bottom line and decision-making of teams. Without knowing the distribution formula, teams do not know the costs of signing free agents or making trades. And my impression is that they are not banging down doors to find out. This suggests that teams either like uncertainty or are still struggling with understanding the full implications of the luxury/escrow tax system. I find both explanations implausible and figure that there has to be something else that explains this behavior. But figuring out what this "something else" is is beyond this writer's mental capacities.

What will the salary cap, luxury tax threshold, and mid-level exception be in 05-06 and 06-07?

By Dan T. Rosenbaum

Every year during July it is a big mystery where the salary cap is going to be set. Now, according to reports about the new collective bargaining agreement (CBA), we will add to that mystery by having the luxury tax threshold also being set at this time.

Under the rules in the previous CBA, along with the reported changes in the new CBA, here are my predictions of the salary cap, luxury tax threshold, and mid-level exception over the next two seasons. (I discuss the calculations more below.) Now, of course, if these assumptions about the new CBA are way off, my predictions would need to be amended.

2005-06

  • Salary Cap - $51.0 million (range of $50.0 to $52.0 million)
  • Luxury Tax Threshold - $61.9 million (range of $60.8 to $63.0 million)
  • Mid-Level Exception - $5.18 million (range of $5.10 to $5.25 million)

2006-07

  • Salary Cap - $49.4 million (range of $47.0 to $52.0 million)
  • Luxury Tax Threshold - $59.9 million (range of $57.0 to $63.0 million)
  • Mid-Level Exception - $5.66 million (range of $5.35 to $5.80 million)

Yes, you are reading this right. I am predicting the salary cap to be higher than the conventional wisdom of $48 to $50 million this season and then drop quite a bit in 2006-07. In fact, if basketball-related income (BRI) is low enough to generate a $48 to $50 million salary cap, then I expect there to be a luxury tax in 2004-05.

That makes me think that revenues came in about as expected or better than expected, which would likely mean a salary cap of $51 million or higher. (But if revenues came in lower than expected, then a luxury tax in 2004-05 is a possibility.)

The reason for these misforecasts of the salary cap is due to peculiarities in how the league computes projected BRI, which is a key component of salary cap calculations. These peculiarities are not well understood by many teams. Thus, last season several teams were surprised when the salary cap was barely changed, despite the fact that it was reasonably predictable beforehand.

The higher-than-expected salary cap this season is likely to throw fuel on a red-hot free agent market this summer. Teams below the salary cap will have more money available to throw at more free agents. Also, maximum salaries for players like Michael Redd and possibly Larry Hughes, Joe Johnson, Samuel Dalembert, and Tyson Chandler are a given percentage of the salary cap and thus will be higher.

The drop in the salary cap in 2006-07 will reward teams who keep their pocketbooks closed this season. There are likely to be fewer teams with less money below the salary cap next season. This may result in more bargains next summer with the caveat that there does not appear a lot of top free agents available.

My guess is that overall this higher salary cap (and higher luxury tax threshold), along with the lack of free agents available next summer, will result in teams being very aggressive this summer.

Notes about the Calculations

Salary Cap:

Salary cap = [Projected BRI * 0.51 - (29/30) * Projected Benefits]/29, where

  • 29 is the number of non-expansion teams in their first two seasons (equals 30 in 2006-07).
  • 51 percent is the salary cap percentage that was increased from 48.04 percent in the previous CBA.
  • I am using $114 million and $120 million for Projected Benefits in 2005-06 and 2006-07, respectively.
  • Projected BRI = Estimated National TV BRI + 1.08 * Previous Season Non-National TV BRI - Previous Season BRI Shortfall.
  • Previous Season BRI Shortfall = Previous Season BRI - Previous Season Projected BRI. (This shortfall is never less than zero.)

Because of a $37 million lump sum payment from Fox Sports to the Los Angeles Lakers that will result in a bump up of BRI of about $64 to $74 million, BRI will almost surely exceed Projected BRI in 2004-05. Thus, the Previous Season BRI Shortfall is likely to be zero in the 2005-06 salary cap calculations.

(Note that without that lump sum payment and the accounting quirks that made it count so much in BRI calculations in 2004-05, there likely would be a luxury tax in 2004-05.)

However, because that lump sum payment will not reoccur in 2005-06, the Previous Season BRI Shortfall is likely to be substantial in the 2006-07 salary cap calculations. And that is likely to result in the salary cap falling in 2006-07. (It will also fall because the number of non-expansion teams will increase to 30.)

This adjustment for previous shortfalls is what causes the lumpiness in the year-to-year salary cap calculations. Every other year there is a shortfall and this results in small increases (or decreases) in the salary cap followed by huge jumps in the next year. This is something that could be fixed in the new CBA - something I would highly recommend.

The new CBA also may decrease the 108% multipler for Previous Season's Non-National TV BRI. That multiplier is an artifact of an earlier period where revenues were growing much more quickly. It is because this multiplier is too high that we get the lumpiness in the salary cap.

Note that if this multiplier is changed or the formula for the Projected BRI is changed, then my predictions for the salary cap could be off substantially.

Luxury Tax Threshold:

I think that the luxury tax threshold will now be based upon projected BRI and thus will be known to teams at the time the salary cap is announced. The only difference between the luxury tax threshold and salary cap formulas would be that 0.51 would be changed to 0.6111.

Mid-Level Excption:

Mid-Level Exception = 1.08 * [Previous Season's League-Wide Salaries/(12.5 * 29)]

  • League-Wide Salaries do not included expansion teams in their first two seasons.
  • 29 is the number of non-expansion teams during their first two seasons.
  • Only injured players whose salaries do not count for salary cap or luxury tax purposes are not counted in Previous Season's League-Wide Salaries.

Now again, the new CBA could (and should) lower the 1.08 multiplier. It may also change the assumption of 12.5 roster spots for each team. I would not be surprised if that increased to 14. Either of these changes would lower the MLE.
