Yeah, Green definitely didn't bulk up. I agree that he's going to play mostly SF. A thin, fast, athletic SF would be fun to watch. If he can fulfill Danny's expectations, I really wouldn't be surprised to see him start at the 3 by the end of the season. I guess it would all depend on how PP would react and accept it.
Unless C Lee is really tearing it up at SG I think AB will get the starting spot back. Although, Lee's size would be nice there.
