If they get rid of the three, why not get rid of the dunk as well? Isn't it a little too easy to score those 2 points by simply forcing the ball directly through the basket? It's not even taking a shot.
I like the three. It extends defenses and adds strategic depth to the game, making it much more dynamic. Why shouldn't there be an advantage to long-range accuracy? Why is it any less worthy a skill than any other? It prevents defenses from packing the box and making every game a contest of strength inside.
Plus it gives most of the white guys something to do.
