Odd are at some point they'd have a shot to get the Eastern division during regular season play at least. Even the Mississippi Bull Puppies won the West back in 98.
This is of course assuming they remain in the SEC, or that the SEC continues as a going concern long term. Or that they even have a football program long term.
They've already got two SEC Championship titles from 1950 and 1976, what with the actual Championship game itself not existing until 1992, so while a rare possibility, at least right now, it's not entirely impossible. I'd rate them as having a better chance then Vandy at least.
