In 2015, for the first time since the Pac-12 split into two football divisions, Troy reigned supreme in the South.

USC made its first appearance in a Pac-12 Football Championship Game last season, and Clay Helton's men don't intend on giving up that Pac-12 South mantle anytime soon.

Use the ranker below to tell us the order which you think the Pac-12 South will fall this season. We'll share the results during the Pac-12 Networks' broadcast of Pac-12 Football Media Days, which begins Thursday, July 14 at 9 a.m. PT/10 a.m. PT.
