I don't think Terrence Jones will bust. I think he'll have some great games and some games where he disappears--like Lamar Odom, but with more consistent effort on D and on the boards.
His disappearing has more to do with getting the ball than desire. Jones has a TON more skill/upside than fanz give him credit for .. somehow, long ago, he became considered a bust and has been the least talked about 10-14 prospect on this board.
