If he doesn't have the ball, what's he doing to help the team win? Does he run the court well? Defend well? Set good screens? Facilitate effectively? What's the point of paying someone $15mm to stand around?
Because in a short Shot clock he is really the only player on our team that can create his own shot. While I agree that paying him $15 million is to much its the contact he came with not the one the Jazz gave him and it seems like most other teams agree with you also. Over payed for what he brings. But he still brings a skill we don't have without him.
