I think you might be right, but to carry my point Carmelo is most times the best player on his team but there are lesser players make other teams better. Petteway doesn't make his teammates better. He wants to take the whole game into his hands and he is no Melo. Both of those players need the ball in their hands so much to be effective that they detract from what the other players can contribute. I don't think it has to be permanent condition, but right now he needs to pass the damn ball and let the game come to him. For now the offense stagnates as soon as he touches it, and by definition motion offenses cannot do that and be an effective motion offense. What is best for him is not what is best for the team. There are times that this team will need him to go get a basket, but it can't be as often as it is right now. The offense operated the most efficiently today when he was on the bench in foul trouble and look at the end of the game again. He does hit a bad three but then misses on three consecutive trips and UAB got much easier looks at the other end of the floor and pulls away.
We know what Mello is. Sample size a little bit too small on Petteway to make that comparison comfortably. It could be that he is being told to do that. It will become more clear as time goes on. I don't think the Mello comparison will end up being valid, but I can at least understand the thought at this point.
