Over the last several seasons, top-tier NBA players like LeBron James, Kevin Durant and Chris Paul appear to be self-selecting themselves onto teams with other top-tier players.
These “superteams” might win a lot of championships, but are they going to ruin the sport for the rest of us? And is there any way to restore more balance to the NBA?
The most striking evidence of this trend may be this: Last season, Russell Westbrook won the Most Valuable Player award while playing for the Oklahoma City Thunder. Of the eight Most Valuable Player awards handed out prior to last year, every single one of those players is currently on one of two teams (the Cleveland Cavaliers or the Golden State Warriors). And all but one of those players switched teams at some point after winning it.
As a result, the NBA is suffering arguably the largest crisis of competitive balance in recent memory. In fact, relative to the other professional leagues, the NBA is already the most unbalanced.
Competitive Balance and the NBA
For any sports league, competitive balance is crucial to keep the game interesting and the fans excited. But it’s not entirely clearly exactly how much competitive balance a league should pursue. Imagine a league with absolutely no competitive balance — team ability is so skewed so as to eliminate any uncertainty in game outcomes. Fans have little interest in watching a sporting event where everyone already knows who will win.

Imagine instead a league where every team has exactly the same ability. Contests, then, are decided solely by chance occurrences: a bad bounce here, an errant referee’s call there. Fans may dislike a foregone conclusion, but pure randomness isn’t much better. Leagues need to find a happy medium.
Relative to the other professional leagues, the NBA is already the most unbalanced. Several calculations exist to try to quantify a league’s competitive balance and, in doing so, allow for comparisons of the degree of competitive balance witnessed across leagues. One figure, called the Noll-Scully measure, considers the ratio of the actual variance in win percentages across teams to an idealized measure of variance. By this calculation, the NBA has historically been the least balanced of the four main North American professional sports leagues.
Another process is to consider a concentration-type calculation (such as the Herfindahl-Hirschman Index) across some sports outcome—playoff appearances, championships, etc. Using these metrics, the NBA again generally finds itself as the least balanced league.How to Fix the NBA’s Problem
So what steps could the NBA take to keep the sport competitive? Several of the most common measures that leagues can employ to promote balance are already in place.
Teams draft incoming players in reverse order of their previous season’s finish, though a lottery can tweak the order a bit. A salary cap is in place in the NBA, meaning that teams are limited as to the total amount of money they can spent on their players in any given season. The NBA also has a system of revenue sharing between franchises.
What’s left to make further improvements? I can offer a few suggestions:
- Transfer control of player allocation to the league itself. Currently, teams have sovereignty over the composition of their rosters. The league itself could take control of player contracts and assign them to whichever teams they see fit. Major League Soccer has a system that somewhat resembles this process (see here for a remarkable flow chart). But I would put the probability of this ever occurring at approximately 0 percent, nor would I think the upside of the gain in competitive balance necessarily outweigh the downside of removing individual team control. Still, if the goal is to increase competitive balance, it is an option.
- Allow teams with worse records to offer larger contracts. As it stands today, the maximum amount a team can offer any player is a combination of a number of factors, including the amount of time the player has been in the NBA and whether the player is re-signing with their existing team. This system gives “home teams” an advantage by letting them offer high salaries; as such, the league could simply instill a similar or greater advantage to teams with poorer records. I’d certainly consider this option to be more plausible than 1), though it would also incentivize already bad teams to perform even more poorly should a particularly desirable free agent be on the horizon. Leagues generally prefer games between teams attempting to win the contest.
- Create easier schedules for bad teams. The NFL has a set formula by which to determine every team’s schedule for the following season. Though only 2 of 16 games are determined by an NFL team’s performance in the previous season, the idea that past results impact your future schedule is not unheard of in professional sports. The NBA could easily tweak schedules to place weak teams on the court against weak teams (and strong teams against strong teams) more frequently. Not only would the variance across winning percentages likely fall, the marquee matchups between the league’s best teams would occur more frequently as well. Of the three options, this seems most plausible.
Whether the current trends of superstars teaming up will push competitive balance in the NBA to new lows remains to be seen. Nevertheless, competitive balance is a tight-rope walk for all leagues — and not something they can ever have complete control over.
As in any complex social system, extending too much control over individual players and teams could ruin the dynamics of the game for everyone. But allowing players and teams the freedom to choose their own paths means accepting that we don’t control all the outcomes — even if that means the Warriors or the Cavs keep winning year after year.
