I agree wholeheartedly. Problem is the only guy that looks like he's going to be able to put on weight is Iverson. Sampson has the same long lean body like his dad, Johnson has been in a college weight room for 3 years so anymore out of him will be a pleasant surprise, and Carter has the same body type as Sampson.
Mbakwe will be a very welcome addition down low to add some much needed muscle along with athleticism.
