Oklahoma ended the 2025 season as college football's sixth-best defensive team based on yards of total offense allowed per game and No. 7 in scoring defense.
Despite losing several key defensive personnel off that 2025 team who are now toiling in the NFL, it's looking like this year's defensive unit might not only be the best yet at Oklahoma under head coach and defensive mastermind Brent Venables, but also the best in the country. And in a football conference as outstanding on both sides of the ball as the SEC, that will pay dividends.
It's amazing but not all that surprising how Venables has transformed the Oklahoma defense from one of the worst at the FBS level to one of the very best. That's what Venables does, and a prime reason he was hired away from Oklahoma after the 2011 season, when he had been defensive coordinator under Bob Stoops for 13 seasons, to lead the defense at Clemson.
Under Venables' direction and leadership, Clemson finished in the top 10 nationally in total defense seven times in 10 seasons and in the top five four times. The 2014 Clemson defense ranked No. 1 in the country in total defense, and in 2018, Clemson led the nation in scoring defense. So it was really just a matter of time before Venables achieved the same thing on his return to OU.
In addition to finishing in the top 10 last season in both total defense and scoring defense, the Sooners ranked third nationally with 45 total sacks and second in the country behind national champion Indiana with 122 tackles for loss. These are the markings of an elite college defense.
Brent Venables, to no surprise, is building a defensive powerhouse at OU
Despite the natural attrition that happens season to season in every college program, Oklahoma remains loaded in talent and experience at all three levels of the defense again this season and has the makings to be even better than last season's outstanding group.
Here's the scary part if you're one of Oklahoma's opponents this season: Venables is looking for even greater things from the 2026 Sooner defense.
"Respectively, it's not a great defense yet," Venables told reporters recently. "We have the opportunity to be a really good defense because we have guys who are bought in, have been developed and have shown enough body of work to give you reason to believe. If they stay hungry and humble, show up every day and put in the work, we have a chance to develop into a really good unit."
Oklahoma's rise to elite defensive status comes with a unique and telling characteristic. All 11 of the Sooners' projected defensive starters began their college careers at Oklahoma. This is a remarkable statistic given all the player options and financial incentives available to college student-athletes today through NIL and the transfer portal. Only one OU starter, sophomore cornerback Courtland Guillory, has been in the program for less than two years.
"None of these guys are portal guys, they're all homegrown, recruited out of high school and guys that have helped us become an elite unit," said Venables said in a recent interview on SEC Network."
Between them, the 11 defensive starters have 27 seasons of collective experience in Venables' defensive system.
"Going from good to great is a small step, but it's the hardest step by a long way," Venables said.
Championship football teams are not built on a whim and a prayer. Whether you're talking about offense, defense or overall, it all starts with the right culture and recruiting the best players available to fit and feed that culture. Few players arrive on campus as ready-made All-Americans. They need to be coached and developed to reach their true potential. And then comes the true test: being able to retain a high level of talent on the roster from year to year to gain experience and continuity.
What Venables and his staff has done with the Oklahoma defense is a living testimony to that operating philosophy and process.
