2009 Egg Bowl, easily.....
There have been a number of games over the years that have set the tone for the next few years, that Egg Bowl domination was one of them.
Others:
2001 South Carolina: Donkey kicked us and set the tone for 6 years of suckitude.
1996 Alabama: This doesn't even need to be explained, sent us rolling towards '97-'00.
1991 Texas: Introduced us to how King Jackie rolled.
This Auburn game, in my opinion, isn't in the same league as those games. It will, however, set the tone for the season, much like 1992 Florida, 1994 Tennessee, 2000 Florida. At the same time, we can still lose and have a great season, much like 2010.
