one and done material. Personally, I would not be surprised to see it be two and done. What left is there to prove. I will tell you this: The Duke coaching staff wishes Frank didn't have to play his senior season and could play for them right now. I have seen direct texts from Coach K that suggest he has nothing more to prove yet you, mister anonymous on an internet message board, claim he has not proven anything yet. I'll take Coach K's opinion and the NBA scouts' opinions over yours, I think. And the Adidas basketball product marketing heads who are doing everything they can within the legal bounds to ensure that he signs with Adidas between Duke and the NBA.
