I think he should. If Vonleh will indeed have a Chris Bosh potential, you don't want to miss that.
But you dont want to play him at Center. If we are drafting a PF, we have to use the other pick and out other young PF's (KO, Sully) or Bass and move it for a Center (Asik is of course THE target) or move up to draft one (Nurkic).
But, wow, with triboy's video, he seems to be allergic on challenging jump shooters...
