I honestly think this is a bad move for him, and no, this isn't the Longhorn fan in me speaking
I don't think his stock will go up any higher next year. I mean, he had a freaking huge year this year which is likely going to culminate in a national championship. Coming back just invites more of a chance for his knees to get blown out again. He is never going to be a first round draft choice, and really should be happy to get picked in by the third.
