Too much scoring, unlike hockey and soccer which don't have nearly enough scoring.

Besides, part of the reason the NBA isn't nearly as good as it used to be is that they allowed too many young players in which diluted the overall talent.

Because as you know young players are smaller, slower, dumber and less skilled overall (which means less entertainment).  The main reason most people seem to love college sports is gambling. Remove that aspect and I guarantee ratings drop through the floor.
