In the realm of unflagged taunting....
I finally got around to re-watching the LSU game. Our first 3rd down play after the half may have been one of the best unflagged taunts I've ever seen. Bear got the 1st down, then bent down and tucked the ball under the arm of a would-be tackler lying on the ground. I doubt Bear knew it at the time, but he was lying injured after being stomped.
Speaking of stomping, I watched both stomps. Watching live, and then controlling the slow-mo myself, if Day meant to do those, he really is Neo. In both cases he jumped while the LSU player was still rolling. On the second one, had the LSU player's right leg gone a little wider, Day's heel would've hit grass, and either way he passed up a prime opportunity to give him a knee to the head and went down instead. The footage we're seeing is the slow-mo as the CBS crew ran it, and they were specifically trying to show the stomps only, and not the circumstances leading up to them.
Generally speaking, the game looked chippy. There was a punt return where one our blockers head-slapped a passing Tiger, and got shoved in the back for his trouble. Neither player was flagged.
