I really believe Braxton will not be healthy enough to get the amount of reps throwing the ball to be seriously considered to be a starter and may never get medically cleared to. The injury he suffered ends the careers of many QBs.
With that said, I love Braxton and do believe he is the most electric player in college football! Urban will have him on the field in some fashion. Running out of the QB spot and even still being a threat to throw short routes and some seam routes but, the long ball will probably not be possible til later in the season.
