My problem with that sequence was at the end of the dunk. Here is a kid who was basically punished for not working hard in practice and doing what is needed to be done for the team. He throws down a hellacious dunk, and stands there screaming as the ball gets inbounded.
For god's sake, are you that full of yourself after getting your hands slapped with a yard stick that you have to bring attention to yourself after a great play?
Make the play, put your head down and sprint back to play defense!
