No. 15 Auburn beat No. 5 Alabama 48-45 in the Iron Bowl on Saturday for numerous reasons, but the final blow was the Crimson Tide's five-yard substitution infraction penalty (12 men on the field) to give Auburn a game-sealing first down with 1:06 remaining.
The Tigers were punting with a 4th-and-4 at that juncture, and Alex Kirshner of Banner Society explained more context behind what happened:
Auburn lined up the punter at wide receiver to try to keep Waddle on the sideline. Bama noticed it late and took a penalty in the confusion. So simple, but so smart by Malzahn.
