If I were creating that site, I would switch those guys. I would predict Thomas as a late first round and Buddy as a late second round. Making All Conference in two conference really impresses me. I also think lots of guys can do what Buddy does. I don't mean to insult him, I just don't think a 6'5" athlete is all that rare these days.
Not saying Buddy can't make it happen, or wouldn't, but Buddy seems like a kid that would come back for his senior year unless he was a top 10 type pick, which I just don't see happening. His body and game, at the end of last year, doesn't scream NBA-fit to me. Again, not saying he can't or won't end up in the NBA, just saying I think he's at OU for four years.
I think most of us forgot that MBaye was a) older, and b) had family that needed supported. I also don't think he was the friendly, loved his teammates type. Nothing wrong with that, but hindsight being what it is, I think MBaye had a few more reasons to leave.
I say that not knowing what Buddy's family situation is like. If his mom is living in a shed in the bad part of town, maybe he does leave early if the guaranteed money is there.
