Honestly guys, BJ is a solid player, we have seen glimpses, but his confidence is rock bottom right now and he can't climb outta that hole.
The man is a solid shooter. A solid PF? Nope. BJ isn't a smart player. He tends to think that he's the star of this team, maybe even a top10 player in the league. He want to be that clutch guy with sec remaining.
He needs to learn how to play the post and in the paint. If YAO MING can develop a post game, hook shot and range, why can't BJ? It's a mental thing. And BJ just doesn't want to learn. He rather believe he's a SF.
