I've seen video of Greg McElroy flipping off Auburn fans during the Iron Bowl. This is a sport built on passion. Mayfield plays with passion. I dare say if he were the Alabama QB you'd be all in. We love him and wouldn't trade him for anyone. He was subjected to a litany of crap from the Jayhawks including an obscene gesture from an assistant coach...not to mention a deliberate hit that was clearly intended to injure him. Whether he does well in the pros is anybody's guess. Regardless, you may think he's a punk but he's our punk and well go to war with him any day.
Your eyes deceived you. I've seen the same video and Greg was holding his mouthpiece in his left hand with his thumb and index finger. He wasn't intentionally sticking the bird at anyone.
The only taunting I remember him doing was the 'Hook-em-horns' at Texas after the BCSCG for not recruiting him. He probably shouldn't have done that but that's fairly mild.
As far as Mayfield we would probably tolerate it but we wouldn't be 'all in'. We are pretty tough on our players often fighting among ourselves when then do something wrong outside of the game.
He's a punk. He's your punk and I understand that Sooner fans will have his back....but he's definitely a big-time punk.
