He seems to be really smart and his finishing package around the rim is surprisingly mature. So I don't know if he takes major leaps and bounds from where he is... but agree he looks like a good rotation center and would be an improvement on a few teams situations.
I don't see him developing the jumper... I think he could be a good roll man without crazy verticality... he seems to catch and finish well. I don't want to sell him short but its also good to be semi-realistic. He has been a nice surprise I'll say that.
Yeah the flip side of being so mature is that it's not as clear where he can make a large development, but he's pretty damn good already. I don't think he will be a guy that's right for every matchup. We've already seen him get the quick hook against spread teams like HOU and DAL.....but considering the success rate on guys picked after the lottery he is proving to be a huge win for us.
