I think he's overrated by Celtics fans, not the NBA. I think he's a top 100 NBA player, which should make him a starter on most teams. I think he's miles away from an all star game, but he's not compensated like one. I think he plays the game with a sense of purpose, and can hit an open 3. He and Smart are probably our best defensive threats versus all star wings.
I like him, but don't love him. I would imagine most non-homers would agree.
