OSD, I'm not so sure he would HAVE to beat GT to keep his job.....he's owned GT during his tenure.
Let's say they win out up to the GT game (9-2), going to Atlanta as the East winner but then lose to GT. He will not be fired.....9-3, SEC East Champs, good bowl? They will definitely keep him especially with his latest success in recruiting.
Now if they are 7-4 and lose to GT, yeah, he's probably gone.
So, imo, it depends on the other games, not so much GT because he HAS been beating them consistently.
