Draft Express had Darren Collison as a second rounder. He went mid-first. Just because a player is mocked in the second round doesn't mean he will last until then.
Pritchard probably felt that Claver wouldn't last to #31. None of us have any way of knowing but, due to track record, I'll trust his judgment.
And I was hoping for Blair at #22 also. In fact, I was anxious at #20, worried that Utah would take him. But after seeing every team pass on him until the mid-second round, I'm less bullish on him. Yes, sometimes the entire industry blows it, but that's not what I'd bet on.
