Although I think he could probably do well at another position, it is his life, and he must follow his own desires.
Coming out of high school highly rated like Suggs, Camp, and many others over the nation, these kids are looking for pro money and pro stardom. It does not always happen that way. In fact, it happens less often than those that succeed.
He may feel he could go to another D1 school and win the quarterback job and go on into the pros. The odds are heavy against this happening, but if he feels that is his desire, then it is up to him.
If he left, he would probably fare better at a smaller college where he would not have to sit our a year and would have a better chance of being the number one quarterback.
Good luck to Bilbo regardless of his decision.
