I'm going with revenge, home-court and the superior defense in this matchup. All these reasons put me on Tennessee. 
The Volunteers have had this matchup circled ever since Florida dealt them their worst loss of the season, 75-49, back on Jan. 19. 
Tennessee is trying to regain the dominance it showed earlier in the season. Florida hasn't been playing that well either, though. The Gators are 3-3 SU and ATS in their last six games. They lost as 4-point home favorites, 72-70, to Missouri this past Wednesday in their last game. 
Tennessee has the stingiest defense in the SEC. The Volunteers rank among the top-30 defenses nation-wide. They give up seven fewer points per game than Florida.
