I thought the game was over twice 
I'm the opposite. Upthread I specified a "neutral fan" because when my team is involved I tend to be one of the last ones to feel comfortable when they are ahead and one of the last ones to give up hope when they are behind.
Once when Ohio State went up 10-0 in the first quarter and LSU was busy bumbling snaps over the QBs head for massive losses, while the MLB refused to stay in his gap and Beanie Wells ran like a gazelle on the African plains.
At that point I was feeling pretty good but I certainly didn't think it was over.
And once early in the third quarter out of the half, when Ohio State stopped LSU's opening possession but then roughed the punter, and LSU continued the drive and scored anyway.
In retrospect that roughing the punter penalty was the dagger. Ohio State had gotten a stop and IIRC it was 4th and a freaking mile. At that point it was a two TD game at 24-10 so a stop and a score makes it a one possession game and they got dinged for roughing, LSU scored and it was a three-score game. I still didn't think it was over because bigger leads have been overcome in less time but it was nearly insurmountable at that point.
I'm going to share my story of that game. So obviously it was LSU and Ohio State for the NC in LSU's home state. Ohio State always travels well. I don't know how well LSU travels typically but it really doesn't matter for a game in their back yard. I had been to a bunch of bowl games before that and when that matchup was first set the prices were astronomical because LSU vs tOSU for the NC in Louisiana is about as high demand as you could get. My brother and I talked about it and decided not to go because tickets were $2k+ for bad seats. About a week before the game demand dropped because everybody had their plans set and scalpers started dumping their tickets so when it got down under $500 my brother and I decided to go.
A friend of ours lived in Atlanta at the time so we got three tickets. The tickets arrived via FedEx while my brother and I were in the driveway waiting to leave. He and I spent a night in Nashville and saw the Grand Ole Opry then met up with our friend in Tuscaloosa and went to the game.
Weird game. The first three possessions almost couldn't have been better for the Buckeyes. It was as you described it: LSU was bumbling snaps on offense and missing assignments on defense and the Buckeyes were up 10-0 before some fans had managed to find their seats. From then to mid-3rd quarter it completely flipped. Ohio State's possessions while LSU was scoring 31 unanswered points were:
Then it got slightly worse AFTER it got to 31-10. Ohio State got the ball back down by 21 and was forced to punt. Punting felt like giving up because it was mid-way through the third quarter but then LSU inexplicably threw a pick. As much as fans complain (as you did upthread) about coaches going conservative this is why. That pick momentarily gave Ohio State life. Ohio State took over at the 11 and punched it in to make it 31-17 which is still bad but not altogether insurmountable.
Then Ohio State forced a quick 3-and-out and got the ball back down 14 early in the fourth and started driving and just when I started to believe . . . The QB got sacked and fumbled. Then Ohio State forced another quick 3-and-out but when they got the ball back still down 14 the clock was down to around 3 minutes and it was over.
My seats:
I would tell you that I sat in the last row of the SuperDome but that is actually an understatement. There is a flat spot behind the last row. It looks like it is so you can walk around there. Anyway, I sat in a folding chair on the flat spot BEHIND the last row of the SuperDome and when I stood on my seat I literally touched the ceiling of the SuperDome.
