At the end of the regular season last year I blogged about competitive balance in the NBA since the 99/00 season. Now I will update this given the end of this year's regular season. For those interested here is a guide to calculating competitive balance using the Noll-Scully method on your own. The only difference here is that I will give both the sample and population measures of the Noll-Scully for this season.
After downloading the data from basketball reference, I found that the NBA is still highly uncompetitive as compared to other sports leagues, with a Noll-Scully of 2.97 (sample) and 2.92 (population). Either way, the NBA is still very uncompetitive relative to other sports leagues.
