Yeah, thats why I said it would behove him to go the Pete Newell's big man camp. Almost every big in the NBA that has gone there has gotten better. But your right, he needs to use his left hand once in while when he drives to his left, just to keep the opposition honest. I saw him use a jump hook in college and I have yet to see him use it in summer league. He has a nice jump shot from 18 feet in. He needs to learn how to do a little jab step and step back jump shot. That shot was Funderburke's bread and butter. With Thompson's height, that shot would be almost unblockable.
But Hey, he has all the tools, he just has to refine them.
