I'm not sure if Florida scores 35 or 55, but I'm pretty sure Tennessee won't score more than 10 offensive points (could get lucky on a kick or punt return or fumble recovery, etc).
Crompton didn't just have a bad day. He is bad. Everyday. Heck, even against Western Kentucky he threw 2 picks. And if you watched the UCLA game, he didn't just "miss" on 13 of 26 passes...I mean they were 6 feet over the head, into the ground 10 feet in front of the receiver, etc, just bad, bad, bad.
For the whole year last year he was about 50% completion with 4 TDs and 5 picks.
The only way they get anything going against Florida is if they can somehow run the ball successfully and ask Crompton to simply not hand the ball off to Brandon Spikes as he's blitzing up the middle. If they can do that and manage some sort victory in the field position battle, giving themselves short fields, then they may put up a few points (14 to 24 maybe?).
I say it's a replay of the Florida / Georgia revenge game from last year (see 49-10 score).
