I idly wonder how 1995 nebraska would fare against an elite modern team. I'm guessing the lines today are 50 pounds heavier, and maybe slower.
The USC-Texas game remains the best football game I've ever watched.
Definitely the best NC game.
For a neutral observer anyway. If I'm a Florida fan, I probably like the beatdown of Ohio State, and the same goes for a fan of any winning team that won big. But if your team isn't playing, it's a lot more fun to get a close one, and none was closer than Texas/SC, ergo, an all-time
neutral great.
Depending on your bent, not all close games may be created equal. LSU/OU was a defensive slugfest, and for people who don't mind that, I assume that was a better watch than a lopsided game. But if those kind of games bore you, then maybe you prefer a higher-scoring, close affair like FSU/AU, or even a lopsided game, to the low-scoring game even if it's a close one.
I don't mind high or low scoring affairs, as long as they don't come about because of inability on the other side of the ball. Pretending I weren't an LSU fan for a moment, as a neutral observer I don't mind the LSU/OU game because both of those offenses steamrolled teams approximately however much they wanted to, but the defenses were just that good. And I don't mind higher scoring affairs so long as they don't come about because the defenses were just bad.
Thus, Texas/SC is the best NC game for a neutral observer, because A) it was close, B) both offenses routinely stuck 40+ on their opponents, C) both defenses were
at least highly competent (I'd say elite, in Texas' case).
