I have said it elsewhere. Losing a game close due to your own internal issues can cause you to refocus and fix things. Losing a game by that much after steamrolling all year can be catastrophic to your morale. It doesn't cause a reset as much as it causes you to question everything.
BTW Guy on Finebaum is saying they win it all by changing to JT Daniels. He can't explain why we did not see Daniels when the game was on the line but he firmly believes that JT Daniels is the missing piece. I also hear others talking about how UGA didn't blitz, with their evidence being no sacks. Some folks didn't watch the game.
