I'll pick 4, thanks
1997: Michigan vs Nebraska - no brainer - Huskers had an offense.
1994: Nebraska vs Penn St - The Lions had a great offense setting NCAA records - Huskers were just too strong in the trenches both sides of the ball. If Warren Sapp, Ray Lewis, Dwayne Johnson and that defense playing at home couldn't stop the Huskers, the Lions would have been in trouble. Since they didn't play the game, I think Joe Pa deserved a share and a split of the title.
1983: Nebraska vs Texas - tough one - Horns had a great defense, played an impressive schedule, and were ranked #2 all season behind #1 Nebraska. Everyone wanted to see this game. Instead Osborne went for 2 in Miami after the Horns had lost to Georgia in the Cotton bowl. There's no way I don't take the Husker's offense in this game. They set multiple NCAA records that season. I didn't think the Horns or the Canes could touch that Husker team.
1970: Texas vs Ohio St - this would have left Nebraska out - Final Rankings: AP (post-bowl) #1, UPI (regular season) #3
On New Year’s Night, all the right dominoes had fallen and coach Bob Devaney’s No. 3 Huskers found themselves playing for the national title against #5 LSU in the Orange Bowl. Tagge stretched over the goal line in the fourth quarter for the deciding touchdown.
