NHL and Competitive Balance

With the National Hockey League (NHL) a little over 24 hours from locking out their employees for the next season, and given that the NHL commissioner has stated that "[w]e've had seven years of incredible competitive balance", I thought that I would look at this statement.  Since the cancelled 2004-05 NHL season, here is the Noll-Scully measure of competitive balance using the binomial and trinomial distribution for both a sample and the population.

Binomial Distribution
Season	Sample		Population
2005-06	1.637		1.610
2006-07	1.600		1.573
2007-08	1.037		1.020
2008-09	1.369		1.346
2009-10	1.274		1.253
2010-11	1.308		1.286
2011-12	1.154		1.135
Trinomial Distribution
Season	Sample		Population
2005-06	1.993		1.959
2006-07	1.947		1.915
2007-08	1.258		1.237
2008-09	1.667		1.639
2009-10	1.562		1.536
2010-11	1.601		1.574
2011-12	1.415		1.391

Recently the NHL has been more competitive, thus supporting the NHL commissioner's statement.
