I'm not so sure Barnes will be a one and done. That's pure speculation. I haven't read any quotes from him saying anything like that. Having said that, I'm no fool. Barnes (at least from the clips I saw of him), is a big time player, and he would be a high lottery pick coming out of high school. I think it's hard for anybody to turn down that kind of money (but then again Davis already did). As for Davis, I do expect him to go pro after this year, but again he hasn't said anything about that. He is much like Hansbrough, in that he loves college. Does he love it enough to stick around for another year or (gasp) long enough to graduate? I wouldn't bet on it, but I'm not Davis and neither are you. The only sure fire bets on who will be gone after this year are Thompson and Ginyard. Henson just looks too raw, and even though the NBA drafts on raw talent, he may choose to stick around and refine his game so he doesn't warm the bench for a couple of years in the NBA.
Yes you never know who will leave and who will stay. I just have a feeling that Davis will be gone but who knows and it depends on the year he has too. I agree with Henson he will need to put on serious weight before he can go to the NBA. I never thought Ellington and Henderson would leave early but they did so you never know. I can't see Barnes staying for more than a year not with his talent. Who was the last # 1 recruit to stay for 3 years? It had to have been before 2002 so we will see.
