One or the other of them has been crappy pretty much constantly since the SEC split into divisions. I remember talking when the divisions were announced about how epic it would be when we met in a rematch for the championship. I was a longhaired college boy then. I'm an old bald man with a house full of kids now.
I think you're correct on this. UF and LSU have never met in the SECCG either, and both have been excellent teams for the last 10 years.
