Looking at just the last 4 Finals is inadequate due to a small sample size. Eleven out of the last 16 NBA champions were from the West. Even the NBA has acknowledged the disparity in that there have been suggestions to change the conference format. Factor in the premise that Western teams are "banged up" by the time they reach the Finals, then that makes 11/16 even greater. Oh, and that last four would have been 3-1 too in favor of the West, had it not been for a Kawhi missed free throw and that Ray Allen three.
