Florida-Kentucky is not the best rival in the SEC. I think that it is Floida-Tennessee.
Editor's Note: Thanks, I'd say you are right now. Now that Kentucky isn't so good, the rivalry has faded. Now UT and UF are 1 and 2 in the conference, so naturally their rivalry has heated up.
Also, there is some spillover from the football rivalry which is also stronger between the Vols and Gators. Agree with you -- for now anyway. One day UK will be back though....
