Because to every good thing comes an end, just like Ax and Smash when Vince tried to stick Crush in the mix.
These are my major gripes that you can chew on. By the mid-90s, fundamental skills and unselfishness were beginning to die out rapidly. Also, plodding, hulking, boring defense laden ball was becoming the norm for less talented teams because it was a hedge against getting nightly beatdowns (prime example: Fratello's Cavs). Now it is damn near THE norm for every team. Sometime in the mid-to-late 90s, players coming out of college were more and more inclined to be high flying dunk artists or 3 pt bombers. Also, the mid-90s saw an influx of kids jumping in straight from high school. No matter how good these players are, they still would be better served to go to college.
