Georgia - which owned the No. 1 ranking before getting crushed on the road at Auburn - dropped to No. 7, putting the Bulldogs in a precarious spot as they attempt to break into the four-team playoff.
Clemson's jump to No. 2 comes as something of a surprise, but selection committee chairman Kirby Hocutt pointed to the Tigers' win over Auburn early in the season as a victory that stands out now more than ever.
Miami, meanwhile, ascended to No. 3, but didn't jump Clemson because it hasn't yet flexed its muscles on the road, Hocutt said.
