LSU and Georgia, for different reasons.
LSU because we were really outplayed for about 40+ minutes (1Q, 3Q and first 10 minutes of 4Q), and Metzenberger had a Garcia game. But we dug down deep and found a way to stop them on 4th down late, and took it the length when by all rights, we should have lost.
Georgia for kind of the opposite -- We played UGA into the ground. That game shouldn't have been close. But mistakes could have killed us. Blocked kick for TD. Fumble going in for a TD, followed by an interception in the EZ, missed assignments letting UGA get out of bounds in their own last drive when they had no time-outs. We made enough mistakes to lose to three good teams. But we didn't. We found a way to make a play late and time ran out with UGA 5 yards short, acknowledging they had no business being within 2 TDs.
In both cases, we had to overcome adversity. Against LSU, that adversity was LSU playing well. Against Georgia, it was our own mistakes.
