NORMAN, Okla. -- In carving up the Big 12's best defense, Oklahoma quarterback Baker Mayfield expanded his lead in the Heisman race.
And in obliterating the No. 6-ranked team, the surging Sooners sent another major statement to the College Football Playoff selection committee.
Fifth-ranked Oklahoma KO'ed TCU with 38 first-half points, then cruised to a 38-20 victory through two sleepy final quarters.
Gary Patterson's TCU defense had given up 24 total points combined in its previous four games, but his Horned Frogs were no match for Mayfield or the nation's top offense.
