Cap. One Bowl would be a nice draw, especially against a quality Michigan State team.
If Auburn goes to the BCS game, the Sugar Bowl will take Arkansas and LSU will probably end up in Dallas which would leave you guys heading to the Capital One Bowl. If Auburn loses USCjr to Sugar Bowl, Auburn gets an at-large, Arkansas to Cotton Bowl, LSU or Bama to Capital One and the other would go to the Outback Bowl. My guess would be Bama would get chosen over LSU if you draw one of the Florida bowls. Bama fans travel like few other fanbases, which may actually work to your detriment if Jerry-World needs to be packed.
Outback Bowl would be the absolute lowest you guys should fall and even that is a push, in my opinion. I figure you'll end up in Dallas or Capital One
