I don't think I have ever seen Vernon Carey play so hard for me to judge. Based on what I read, all his numbers look good. I put him in the same category of several of the other top end big prospects such as Toppin, Okongwu, Achiuwa, Stewart, Smith... that we may well have a shot at. (I have Wiseman in a different category)
Any of these could emerge as the best of the group or maybe someone else. You just don't know. None of them are locks, but all of them have enough potential that they could be really good. One, if not several, of these bigs will be available at 26 and maybe even 30. I don't know which one will be the best (I actually like Isaiah Stewart as a sleeper), I just hope the Celtics pick one or more of these and somehow get it right.
