I don't believe so. The general consensus is that he is a solid player, perhaps an All Star. That is about right. He is not an upper echelon player, superstar, or one to take over a game. However, he is one of the best PFs in the game right now
I don't see how he can be overrated considering nobody ever talks about him...he's obviously a very good player.
He was mentioned in the MVP Balloting, and he is only like 25, he will contribute to our team in years to come.
