Let's preview the outlook for the Big 12 this season, according to our Power Rankings:
Last season's record: 11-2
Key returning players: QB Baker Mayfield, OT Orlando Brown, CB Jordan Thomas
Key losses: RB Joe Mixon, RB Samaje Perine, WR Dede Westbrook
Reason for optimism: No returning FBS QB has more career wins than Mayfield, who will be operating behind an offensive line as stout as any in college football. The defense also quietly improved down the stretch last season.
