I'm going to have to disagree with the analysis on the play where JG fumbled. They were lined up in man to man with 2 high safeties. The safety on the side that's blitzing starts to cheat over pre-snap, they then go man to man after the blitz with a single high safety and the safety that cheated over sliding into man to cover the receiver the blitzing corner left open. It should have been obvious to JG they were blitzing from that side when the safety started to cheat over. The idea that the offense couldn't have figured it out if they hadn't seen that blitz before on film is nonsense.
Go to the 13 second mark and look at how the safeties are lined up and see that the safety on the blitzing side is shifting into position to cover the UT receiver in man.
