It didn't end up mattering to the end result, but the sideline interference call Alabama was hit with right before halftime was about as frustrating as a penalty can get.
It wasn't a coach. It wasn't a player. But Alabama was penalized because someone way down the sidelines made contact with the official. And it was directly after Alabama had made a third-down stop, which was forcing Oklahoma to punt and put the ball back in the hands of the Crimson Tide offense with about 30 seconds to go.
Alabama had all the momentum, rallying from a 17-0 deficit to tie the game on Zabien Brown's pick-six just a minute earlier.
