I was thinking Vanderbilt myself. The Commodores last win was way back in 2019 against Missouri but had previously lost 23-straight SEC games before winning in back to back games against Kentucky (who probably had a let down after their Georgia loss) and Florida.
A combination of us not being very good now along with some of our opponents being greatly improved. Tennessee, LSU, FSU, and Arkansas to name a few.
Why is S Carolina that much different than us? Swap out Clemson for FSU and we get LSU out of the west and theirs is easier. Is the LSU game the only difference? Maybe it's the home versus away schedule.
