Will you trade 2 first round picks for him, ala Mosgov?
Not yet.
I think there's a little bias from me if I say I will. I'm completely sold. I think there's enough sample size to suggest that, at worst, he'll be, well, Mosgov. At best, I think were looking at a better Roy Hibbert.
Defensively, perhaps, especially since Whiteside actually has lateral quickness, athleticism, and excellent speed, but not offensively (at least not yet). Hibbert is an excellent passer and post player, while Whiteside has only shown flashes of such ability. Do I think he will improve? Yes, particularly due to the fact that he can already use both hands on the block. Get him a great big man coach, and he could be a faster, more athletic Andrew Bynum, without the attitude problems or knee issues. Thanks, Danny (sarcasm)! Ugh.
