College coaches of weaker teams figured out a long time ago that the 3-pointer was a great equalizer - if my team makes a three every time down the floor, and your bigs only score two on your trips, who wins the game?
So of course that percolated up to the pro game as well. To the detriment of both games IMHO.
Anybody can be a good three point shooter with enough practice.
Try threading a pass inside for an easy layup.
