Everyone seems to think Nebraska still wins the NC with a tie there. Voters back then were idiots and cared more about WHEN you lost or tied as who it was against.
Auburn finished their season with consecutive wins over teams ranked 5th, 7th, 4th, 19th, and 8th. Their only loss was to top-5 Texas back in September.
I think Auburn wins the NC (or at least a split) if Nebraska tied in the bowl game.
