During Oklahoma’s Lincoln Riley era, the Sooners dominated Texas. Riley went 6–1 against the Longhorns, including a victory in the Big 12 Championship Game on Dec. 1, 2018. However, things have been different over the last half-decade.Brent Venables took over as the Sooners’ head coach in 2022, one year after Steve Sarkisian became the Longhorns' lead man. Texas is 3–1 since Venables was appointed, with an average margin of victory over the Longhorns’ three wins of 32.3 points.Texas is looking to extend its winning streak to three games for the first time since 1997–99. Oklahoma has one clear advantage, and while it has not mattered in previous matchups, it could define the 2026 edition.Oklahoma’s Defense Could Cause Texas-Sized ProblemsOklahoma Sooners defensive lineman Taylor Wein in the first half of the Red River Rivalry college football game between the Sooners and the Texas Longhorns at the Cotton Bowl Stadium in Dallas, Texas, Saturday, Oct. 11, 2025. | SARAH PHIPPS/THE OKLAHOMAN / USA TODAY NETWORK via Imagn ImagesWhen Oklahoma’s defense lines up against the Texas offense, the two best units in the game will be on the field at the same time.When it comes to the Red River Rivalry, it often feels as though preconceived notions about the team are irrelevant. The intensity and familiarity set both teams back to the basics. However, the matchup of the Longhorns' offense and the Sooners' defense will likely define this season's rivalry game.Last season, Oklahoma was carried by its defense to the College Football Playoff, with its offense doing just enough to get the job done. The Sooners were 79th in points per game (26.2) while allowing the seventh-fewest points per game (15.5).There is optimism that Oklahoma’s offense will improve. Quarterback John Mateer could take the next step with Parker Livingstone and Trell Harris coming in to catch passes. However, the Sooners' defense has been among the best in the country during Venables' tenure and has come to characterize the program — a far cry from the Riley era.Oklahoma Sooners defensive lineman R Mason Thomas and linebacker Kip Lewis celebrate during the game between the Texas Longhorns and the Oklahoma Sooners at the Cotton Bowl. | Jerome Miron-Imagn ImagesUnder Venables, Oklahoma has ranked inside the top 20 in each of the last three seasons in adjusted EPA per play allowed. Last season, it ranked second behind only Texas Tech, according to GameOnPaper.
