So many. But the ones that stand out are:
1990 - at Virginia.
Sisson making that kick was worth the ensuing Charlottesville curse, which hopefully has now run its course.
1990 - Citrus Bowl.
Was there in person. Also, fun to have on the list, as I now am married to a Husker and see some links to both programs.
2014 - UGA.
That game was a rollercoaster, from start to finish. I watched it with my wife and in-laws, who were just as engrossed in the game as I was.
2015 - FSU.
Damn, we needed that one in the midst of an awful season. I didn't get to watch the game live - but my wife was watching it from a hotel room on a trip with her mom, and got so loud yelling at the end of the game that someone called the front desk to come check on them. She didn't tell me anything about it until after I had watched it - when I asked her how the game was, she just solemnly said, "You need to watch it."
