Tim recently said that one of the big benefits of being at USC was that he could go watch games and recruits at practices, and still be home for dinner. Now, if you remember what his wife Beverly looks like, I'm thinking that USC has one huge advantage.
Besides, he has an immense amount of talent returning next season (even more than OKState does), and the #2 player in the class coming in in Demar DeRoazan. As long as OSU doesn't have Gary call Tim up, I don't think he'll go anywhere.
