For Florida, they just need to keep doing what they're doing on defense. These UGA receivers are probably the best they'll have seen, but Florida's secondary is probably up to the task if the front generates pressure the way they have been. UF ranks very well against the pass in my little ypp index thingy, and is also pretty stout against the run. What vaults them to the top of the conference in that formula is they've been very good at getting the ball. They've got some INTs but also recover fumbles at a phenomenal rate, best in the league. Fumble recoveries are largely luck, but causing fumbles is not necessarily, and the more you force the more opportunities you have, so it's reasonable to expect UF's defense to help field position in that respect.
Offensively, UF probably just needs the same type of game it got against LSU. Assuming the defense is playing well, it's okay if the plays don't all work, Mullen just has to get that handful of perfect calls and Florida needs to execute them. Neither LSU nor UGA has shown up as worldbeaters on defense in my metric so far, but they're both pretty good and roughly equivalent. Florida needs to do what it did to LSU....drag this game down in the mud, force the Bulldogs to play their game, frustrate them and nail those opportunities when they open up.
I don't think UF can dominate this, but I can see them grinding out a close win similar to vs. LSU with roughly the same gameplan. That's important because it isn't asking Florida to get out of its comfort zone. If they can slow the game down, they don't need flukes to win, the chances will probably go in their favor just as vs. the Tigers. The defensive front will be key, though....I don't think UGA's OL is going to gift them as many plays as LSU. The performance of the Gator D-line is big, I'll say the main hinge of the the game from Florida's standpoint.
I'm wrong a lot, though.
