I thought I was seeing things at first but I brought binoculars to the game and I saw fans flipping off back, or at least doing something in return (I assume the returned the favor) I saw one finger up, it looked like he was saying Auburn was number one and he wasn't using his pointer finger to say it...
(yea I'm sure he would just randomly hold up his ringer finger or pinky finger, because that means everything in society today *rolls eyes*)
