You're doing what the typical uninformed fan does. I agree, if all you are saying is that it's not an impressive resume, but that's not we're discussing. We are discussing Vandy being on the bubble, where EVERYBODY has a non impressive resume.
The real question then becomes; How does Vandy's resume stack up against other bubble teams?
As for winning at aTm, it's not a great win, but winning on the road against a top 100 team is a good win, not a great win. Winning at Florida (a UK fan should know how good of a win that is) and at Arkansas are very good wins, as are beating USCjr and Iowa State.
