It's not that Stephon Marbury was injured or even that overrated. In fact, for a spell, he was one of the league's top point guards. He was just batshit crazy. Immediately after the trade from Phoenix, New York rejoiced at the return of their prodigal son. Then they got to know him. Marbury feuded with coach Larry Brown, contributing to Brown's untimely firing. Then Marbury feuded with GM Isiah Thomas over his minutes and starting position, including rumors of a fistfight, blackmail and a sex scandal with Knicks employees. Thomas was fired and replaced by Mike D'Antoni, whom Marbury also bumped heads with over minutes and playing time. Finally, New York had enough. They couldn't trade him at this point, but the problem became so bad that Steph was banned from team facilities, essentially earning $20 mil a year just to go away.
