When Iverson has the ball, the whole team tries to keep away from him as they let him go isolated. If you move toward him when he has the ball, all that happens is he gets clogged up.
He should be more aggresive when Webber has the ball, because he is a quality passer. A problem with that, though, is that if you run isolation for AI and then Webber gets the ball it takes time to get across the court to him. At which point the ball will probably have been moved already.
Which makes me think that maybe he doesn't fit into the Sixers program, he needs more offensive freedom. After watching both guys yesterday, I'd love to see CP3 and AI2 on the same side. My two favourite young players, and the two most talented on the floor yesterday.
