I'm higher on Griffin than you are I guess.Even though I don't love some of those guys (I think Duren and Griffin are the only ones I'd be a lot lower on) I think those guys are all great bets. Last year I didn't care much for Mitchell or Bouknight really much at all... outside of Moody and Duarte there weren't guys I really liked in that range... just didn't seem like there were a lot of guys I thought were surefire rotation players. I'd feel pretty good that if I had two picks in the teens I could come out with at least one average starter quality player and a rotation piece... and think both would have upside for more.
I think he has an elite skill. That's more than I can say for most of this draft class. Plus he has the "he's been consistently injured" kind of upside.
