Honestly, after today, I'm not sure that I want him at State.
Knowing Croom like I do, I would not at all be surprised if he doesn't allow him to come back. Even if he does come, I think this could possibly be a big strike against him as he will likely be competing against another QB, probably Tyler Russell, and since the QB is supposed to be the leader of your team, I would definately question his loyalty, at least a little bit at first, not to mention his ego.
So, my answer is this- no. Even if he backs out of LSU, I think Croom will still reject him.
