I stumbled across this neat little summary of the most recent decade of NBA basketball on Basketball Prospectus. If anything, it makes for an interesting read and could inspire some debate in several areas. enjoy! http://www.basketballprospectus.com/article.php?articleid=532
interesting though i would probably put in at 1 or 2 for the biggest rule change: allowing semi-zone defenses. imagine yao being allowed to see single coverage only up until he gets the ball?
