Good on Pop for defending his player, but I'm gonna disagree with all of you here and say that I think Bowen does step under shooters after they are up in the air and he should stop doing it. He shouldn't change his D, but he should NOT step under shooters and he does it all the time. It's very dangerous and has already led to two serious sprains (one incident is isolated, two forms a trend and three or more a pattern).
I think the reason why he does it is much like the pretend punch to the balls that some guys will give you when you go up for a jump shot - instinctively, you are put off.
Go back and re-watch some games over the last 3 years... Bruce can do whatever he likes, but stepping under shooters, which I have seen him do (in the Carter incident he did it quite clearly), is bad karma.
TIME TO COURT MARTIAL THE COMMIE.
