Here are five things to watch as No. 1 Alabama takes on No. 4 Auburn in Jordan-Hare Stadium for one of the South's biggest rivalries: The Iron Bowl.
Big-game jitters: Alabama has been through this drill before. Big games are nothing new to the veteran Crimson Tide. AJ McCarron doesn't buy into the hype and neither does C.J. Mosley. For them, it's just another game. But for Auburn, this isn't just another game. Gus Malzahn has said all the right things, but there's no denying that this is the biggest game of his tenure as the Tigers' head coach. It's a moment for Auburn to prove it's more than lucky. It's a chance to earn a reputation as a championship contender. And frankly, Auburn's players have never had to deal with that kind of pressure. How will they respond? When Nova flies around Jordan-Hare Stadium and the buzz reaches a fever pitch, will Auburn keep its emotions in check or allow them to run wild?
McCarron for Heisman: The momentum is gaining quickly. But is it too late for McCarron to become a serious contender to win the Heisman Trophy? Given Jameis Winston's off-the-field entanglements and Johnny Manziel's three losses this season, the chips are starting to fall McCarron's way. His numbers are impressive (2,399 yards, 23 touchdowns, five interceptions), but has he had the kind of "Heisman Moment" that can catapult him to victory? You could argue his performance against Texas A&M was up to that billing, but that was so long ago and his game against LSU didn't exactly intrigue would be voters. If McCarron is going to win the Heisman, he'll have to do it on Saturday afternoon against Auburn. A big game on the biggest stage might be the final push to send him into the forefront of the Heisman race.
Protecting the quarterback: As Auburn defensive end Dee Ford told reporters this week, "You change the game when you get to the quarterback." Make no mistake, the Tigers defense plans on pinning back their ears and getting after McCarron on Saturday. And with Ford, Nosa Eguae and Carl Lawson at defensive end, they have the tools to do it. Alabama has faced good defensive lines this season (Virginia Tech, LSU, etc.) but none had the type of edge rushers Auburn possesses. As Ford said, "[McCarron] hasn't been hit all year, so we want to see what he can do after being hit a few times."
Who starts at center?: A sprained knee has Alabama starting center Ryan Kelly as a game-time decision, according to coach Nick Saban. He hurt the knee early this week and was limited in practice since then. Saban stopped short of saying that backup Chad Lindsay would start, but you've got to believe the staff has confidence in him after already starting three games this season. “Chad Lindsay did great when he played and we did great on the offensive line,” Saban told reporters on Wednesday. “We have every confidence in him, we view him as a starter.”
Perimeter tackling: This isn't a game where the front seven will do all the work. Alabama's secondary will have to put a hat on a hat to be successful against Auburn's vaunted running game. Nick Marshall and Tre Mason aren't the only two guys that can hurt you. As one SEC head coach told me, the trouble with defending Auburn is that there are five or six guys who can run the ball from anywhere in the formation. Defending the end-arounds, fly-sweeps and other perimeter runs will be vital for Alabama. Because of that, look for safety Landon Collins to have a big day. He's one of the best on Alabama's defense in terms of reading the play and closing speed.
