I'm a bit torn between the two on who could be more valuable to the team. With Alexis he has great size at 7'2 with a 7'9 wingspan and that alone affected so many shots this season. He's skinny as a rail and fouls a lot but if he bulks up and cuts down on the fouls he would be a really good role player. He also has a pretty decent midrange game to help space the floor. On the other hand Withey is pretty athletic and a much better shot blocker and younger. He's also pretty skinny and needs to bulk up because he had plenty of trouble finishing with contact. I'm not too sure on his offensive game but from what I read lately he has pretty good feet where as Ajinca is a stiff.
