Tyson shouldn't have been an All Star last season nor should he have been anywhere close to any of the defensive teams.
Noah, Howard, Garnett, Duncan, Hibbert were all better defenders at the big man position.
He is the only big man in the NBA that doesn't have one move that he can go to. He rarely ever scores if there isn't a wide open putback or a lob pass. He has gotten sick the last two years in the playoffs, which is a problem if you're playing big money for a guy that can't perform when it counts.
