I wouldn't take Randle. His game just doesn't impress me.
He's a good rebounder yeah, but he's relatively undersized at the 4 and has a pretty weak jumper, has limited post moves - the only reason he dominates against college talent is his physical size, which will no longer be an advantage once he moves to the NBA.
He's like a more athletic version of Sully without the jump shot, the IQ, the post proficiency or the passing skill.
I'd kinda like both Sully and Olynyk over Randle right now. If it came to us to choose and he was next up on the board, I'd skip him and select Vonleh or Gordon (who reminds me of Gerald Wallace in his prime).
