As GAVol said, their OL is weak and I think our DL is improving, esp. Dan Williams and the younger DEs. However, my decades long concern is that we are almost eerily bad on 3rd down, esp. 3rd and long.
We're last in the SEC in 3rd down defense, and that is against UCLA, UAB, AUB, and NIU...4 very poor offenses. I think our defense is appearing OK against poor offenses, and even then we can't get anyone off the field.
My guess is GA's skill players are sufficient to ring us up for at least 20 pts, which is more than enough to breeze through this game.
