Davis right now weighs 225 pounds, and he was a freshman. In three years at North Carolina, Henson went from around 185 pounds to 220 pounds, and I think that posted weight is being generous. Henson has narrow shoulders and appears to be small boned, whereas Davis has wide shoulders and appears to be large boned. My gut tells me that Henson would have a hard time being a regular starter in the NBA. I'd rather put my eggs in the Whiteside basket than gamble on Henson.
Look, I'd love to have a shotblocker, but I'm not about to pass over better talent on the chance that a guy with that skill will find a way to add 25 pounds of muscle. We need to draft a player thats ready to play in the NBA right now. The more skills the better. If you going to take a gamble, then take one on Meyer's Leonard.
Henson: Junior, 6'11", 220 Lb's, 29.1 MPG, 13.7 PPG, 50.0% FGP, 9.9 RPG, 2.9 BPG.
Leonard: Sophmore, 7'1", 245 Lb's, 31.8 MPG, 13.6 PPG, 58.4% FGP, 8.2 RPG, 1.9 BPG.
The biggest difference between Leonard and Henson is their developed skills. Leonard is more raw. But I think Leonard is the better overall athlete, and he certainly looks like an NBA center, body wise. He has a great frame, and could easily add 15 to 20 pounds of muscle. And lets remember, Henson was asked to patrol the paint while Zeller did most of the physical man defense under the basket. Leonard had to do both.
Now I could be dead wrong about this, and to be honest, I'd hate to bet my immediate future on either of them. But long range, I'd rather gamble on Leonard. However, if I'm picking down in the 12 to 14 range, I'm taking Moultrie. He may not be the shotblocker you want, but he can play right now, and he is a good defender.
