I read where Wednesday is the last day to enroll, which I take as the deadline for him playing at Bama this season.
Now that said, and noting that he has 3 to play 2, there is no reason that he could not enroll for spring semester, participate in spring training, and play two seasons for us. Yes, but he will have not had any football contact all fall. True, but that is similar to any player who misses a season for surgery. Keep in mind that he has had the play book since his commitment. If there ever was a case where this could work, its Duron.
He has great size and good speed, which will not be lost. He plays WR which is one of the positions that can be practiced without the benefit of a team. He has a super football-smart day with enough money to afford him the chance to be his Receiver Coach for the year. Or, he can afford to live in Tuscaloosa during the fall, where he hangs out with his friends who happen to be football players. But for team meetings and scout team reps, this looks similar to a Red-Shirt year.
