TMG is going to be a very good player. He needs to drop 10-15 lbs and get in a little better shape. The skills are there but you just don't see basketball players carrying the extra body weight he is.
He needs to get on the Lance Armstrong program. Lance dropped 20 lbs and started winning the Tour. TMG needs to do the same. He won't lose any of his talents but his quickness and endurance will explode.
