1st of all, I would be slow to say that this situation is indicative of Memphis or the players involved. Emotions were high, and people respond differently when the stakes are so high (perceived or real). I don't know the young men involved, but I don't think it's fair to judge them from this situation. What this situation suggests to me is that the guys have not been exposed to how to handle certain situations appropriately.
Memphis has its problems, as do most large metropolitan areas, but kids are not the problem. The problem is that no one tries to "control" them until after their 1st dunk, then everyone wants to "control" them. Parents, Teachers, fans, AAU Coaches, High School Coaches, Alumni, etc. These same stakeholders have to get involved while the child is still dribbling with his mouth not with his hands.
