Why did I put a line there?
Above the line, every program has at least 2 wins (SEC Championships)
Below the line, every program is winless
So while the Hogs have been there 3 times, they were held to a FG twice (didn't compete). In all the games by the have-nots (6 in total), none have come within 10 points of a win (and 3 have been massive blowouts).
