I'll never root for UF.
But if they were somehow to beat UGA on a fluke and it saved Mac's job for the next three years, I wouldn't lose any sleep.
I would not shed any tears if the Gaytors served as the grenade that blows up on UGa, and allows us to move up another spot in the rankings.
No reason to root for UF. UGA's schedule will take care of itself. Either they'll lose in the SECCG to Alabama and be eliminated from the CFP, or they'll beat Alabama and Alabama will be eliminated. As far as we are concerned, it's highly unlikely we make the CFP unless we go undefeated. Maybe, if we lose a close one to VT but win the rest and win the ACCCG (would require another conference loss for VT) then, we might have a chance if we get help from other teams, but with only 12 games that will be difficult.
Long story short, just root for UGA to destroy UF!
