Reading this thread, I'm guessing some folks haven't followed the Tua/Hurts saga over the last couple years. Quick refresher:
Hurts was the starter for like 3 seasons, going something ridiculous like 37-2. Tua shows up on campus last year, and everyone can tell he's the better player, but Saban sticks with Hurts until halftime of the Championship. Goes to Tua who leads them to victory.
Hurts, in a move that almost nobody would have thought possible in today's world, decides to forego his own personal interests, and stays at 'Bama this year, even though Tua was named starter. Tua has an incredible season, is the Heisman front runner, and by all accounts, Hurts has been a model teammate throughout it all.
Now Tua gets hurt, and Hurts gets his chance to come back in, and he just led them on a game tying drive in the SEC Championship.
If it were a movie, nobody would believe it.
