Though its not always as it seems. You recall Lagarett Blount's (sp) punch against the Boise St. player that taunted him - supposedly the player called him a n****r, in which case I'm glad he got hit.
So who knows what happened/was said. He seemed pretty pissed.
I agree with you, it was the second victory formation play to run out the clock, and thanks to poor camera coverage we could'nt see the play at the line. The game was over, so for a player, especially a lineman, to get that upset, either something was said or a def lineman took a cheap dive at his knees or a cheap punch. Cut him some slack folks he isn't the kind of player that is negative to his team mates. Something happened on the last play.
