"He's gotten craftier," said Rivers, who also noted his improved shooting and ball-handling. "I think just his smarts have improved. He's got the Dwyane Wade pump fake going now. He gets someone every game on it. He gets a backcut a game and gets buckets that way. So he's not just scoring on raw ability and athleticism. He's scoring with his brain. And to me that's the step that superstars take."
