I also think that this boiled over because Self was already pissed about the lack of rebounding and hustle from his team.
I agree.
I'm not for what Greene did by any means but I also don't care what a kid did who only played 5 minutes does during the last 10 seconds of a game if the other team is just going to leave him completely open. I think its more classless to say what Self said than the actual dunk. You want to apologize for the dunk, fine. But leave it at that.
