I was not watching the game, but listening to the radio broadcast. That certainly changes perceptions and reactions (ala the 1960 Nixon-Kennedy debates).
For me, listening (as opposed to watching) either lessens the emotional impact of negative events, or provides a bit of buffer between the facts of the event and my emotional reaction to it.
But on the other hand, I'm old enough to bear the emotional scars of devastating losses to Florida as far back as the 1969 Gator Bowl--after which they also took our program-saving head coach!
With those caveats, my feeling at the moment of the Florida TD was not the emotional collapse of "Screwed again!!" but more like "Drat. I guess we're gonna have to do this the hard way now." But if I'd been watching it happen, I'll bet mine would have been the emotional collapse of futility.
A neurologist would say that's because images bypass our rational brain areas, and the reason why they're so powerful (and manipulative).
The next thought/feeling I had was to fervently hope that Florida would not decide to go for the two-point conversion. I think I felt nearly as much relief when Florida eventually lined up to kick the PAT as when Sampson actually won the game. For whatever reason, I felt like they were going to be successful if they'd gone for two. (The next day, when I saw the trick formation they lined up in, I felt that even stronger!)
Once Florida decided to get the sure tie and go to overtime, I felt much more positive about Tennessee eventually winning the game.
