NBA Competitive Balance

Yesterday I blogged about the relationship between pay and performance in the NBA.  Today I want to look at competitive balance in the NBA.  For those interested, here is a step-by-step guide to calculate the Noll-Scully measure of competitive balance.

Since the 1999/00 regular season here is the results.  As you can see for the 2013/14 season the NBA's level of competitive balance is very similar.

Season	Noll-Scully
1999-00	2.916
2000-01	2.846
2001-02	2.495
2002-03	2.612
2003-04	2.465
2004-05	2.803
2005-06	2.469
2006-07	2.396
2007-08	3.056
2008-09	3.117
2009-10	2.951
2010-11	2.910
2011-12	2.537
2012-13	2.811
2013-14	2.853

Compared to other leagues (American football, hockey and baseball) the NBA is fairly uncompetitive, with higher Noll-Scully measures than any of those leagues during the same time period.
