This game is really no bigger than Florida and Georgia in 2010....
Auburn isn't even ranked, and MSU is favored. It will be huge to get that SEC West victory, I don't underrate that accomplishment, but its really will be just a small step forward.
As far as ranking the importance of this game compared to other seasons? Its way down the list. You can pick any number of games from 1998-2000 as more important, and any Egg Bowl in which a bowl bid was on the line. That's just for starters. The upsets of Auburn and Alabama in 1997 probably rank higher as well. Heck, the wins over Alabama in 96, 97, and 98 are probably all bigger.
