Three weeks into the season, SP+ ratings are still made up primarily of preseason projections -- there just isn't enough data to make grand conclusions yet. That will begin to shift next week. That said, there's always some interesting movement, and the most noteworthy move this week was just a one-spot jump.
Georgia absolutely demolished an Arkansas State team that came into the week ranked 60th in SP+. The Dawgs raced to a 34-point halftime lead and ended up nearly tripling the Red Wolves' yardage (656 to 220) in a 55-0 win. That bumped their rating from 30.
