2017 — Oklahoma 41, TCU 17
When Oklahoma and TCU played three weeks earlier in Norman, the No. 5 Sooners prevailed over No. 8 TCU by a score of 38-20. As the top two teams in the Big 12 in the 2017 season, the Sooners and Horned Frogs met a second time that season in Arlington, Texas, for the conference championship.
For the rematch, a second top-10 matchup within a month between these two teams, Oklahoma had moved up to the No. 2 position in the national rankings, while TCU remained in the top 10 at No. 10.
Oklahoma led 17-0 after one quarter, but TCU fought back to get within seven points, 24-27, at the half.
The second half was all OU, however, with Baker Mayfield and the Sooners tacking on 17 unanswered points against one of the best defenses in the Big 12. Mayfield completed 15 of 23 passes for 243 yards and four touchdowns with no interceptions. Oklahoma accounted for 461 yards of offense in rolling to a 41-17 victory and the No. 2 seed in the 2017 College Football Playoff.
The win marked Oklahoma’s 11th Big 12 championship overall and first under first-year head coach Lincoln Riley. It also signaled that beating a team twice in the same season may not be as difficult as it might seem.
