What worries me is that after six months with the team KG's having to tutor him in being aggressive by getting him to understand what that feels like. That's pretty much how Helen Keller was taught to speak, wasn't it? It really seems to suggest that Clifford Ray hasn't got through to him on it at all.
Wouldn't you think POB could just go overboard on aggression until he gets it under control? We see him being very active when he plays, and getting pushed away by bigger, stronger guys under the basket, but not really putting up the good fight against those bigger guys.
