I was home all of last week with sick kids, so I've also been watching a bunch of old games. I've had a morbid fascination with the heartbreaking losses, but here are some of the wins that I've watched recently and really enjoyed:
1982 Iowa @ Nebraska (keep an eye out for "Bobby" Stoops playing Safety for the Hawkeyes and having the unenviable task of trying to cover Irving Fryar):
1983 Kickoff Classic: Penn State vs Nebraska:
1976 Bluebonnet Bowl: Texas Tech vs Nebraska (this one is long, but cool, because it has the original commercials):
1980 Sun Bowl: Mississippi State vs Nebraska:
1987 Sugar Bowl: LSU vs Nebraska:
1983 Orange Bowl: LSU vs Nebraska:

1972 Orange Bowl: #2 Alabama vs #1 Nebraska:

Besides the last one, those are some games that people don't talk much about anymore. Other than the first two and the last one, they're all close games, too.
If you want some great games that will still break your heart, decades later, let me know, and I'll give you a list of those, too.
