NORMAN, Okla. -- Last season, the Oklahoma offense featured one of the best running back tandems in the country and a Heisman finalist at receiver.
But to replace Samaje Perine, Joe Mixon and Dede Westbrook, the Sooners could be relying on a running back coming off back-to-back season-ending injuries.
And a receiver checking in at 148 pounds on the official roster.
Baker Mayfield is back for Oklahoma at quarterback after a record-breaking campaign. The entire offensive line, along with tight end Mark Andrews and fullback Dimitri Flowers, is as well.
