Makes sense considering the uncertainty at QB and in the defensive backfield. Considering their other win total picks, you have to think they are seeing UGA loosing 2 or 3 of Clemson (9.5), Auburn (9.5), Missouri (9.5), and South Carolina (9.5).
Other win totals of interest:
Florida - 7.5
Tennessee - 5.5
Alabama - 10.5 (tied with Ohio State at highest in nation)
Looking at the schedule, I can't argue with that, so they are seeing UGA, Missouri, or South Carolina representing the East in Atlanta.
