13 Results Draft –Insignificant –Lagged insignificant Metro –Insignificant State Income Tax –Significant and negative

14 Conclusions Results Indicate –Prior years are good predictors With possible parity effects taking hold in third year Small window of opportunity –Coaching change seen as negative in short term –State Income Taxes Negatively Influence Winning Percentage Affect a NBA Franchises to acquire ability in Management/Owners, Coaching and Players If Parity Is Desired Outcome –NBA could adjust individual team salary cap with index to compensate for taxes and/or cost of living CBA implications
