I think right now the game is still going a little fast for him. And he is a bit hesitant. When his confidence (shot, being in the right place, knowing where to go with the ball, etc.) comes back, I think it will be almost like a switch was flipped. Not saying he is going to become great overnight, but I think there will be a night/day difference.
I have noticed since the first couple of games that he seems to be on the losing end of every questionable call. I think that is related to the above. He is often the just a tad late in responding to a loose ball for example. I think even his body language just gives off the vibe of uncertainty. I think that is part of what leads the refs to whistling him when something is questionable.
