Oklahoma Sooners Football disruptive edge rusher R Mason Thomas joins the Chiefs, bringing an aggressive mindset and game-changing pass-rush ability to the Kansas City Chiefs as their latest NFL Draft pick
With the No. 40 overall pick in the second round of the 2026 NFL Draft, the Kansas City Chiefs selected Oklahoma Sooners defensive end R Mason Thomas.
Thomas, who helped define Brent Venables’ aggressive defensive identity in Norman, heard his name called and officially transitioned from Sooner to Chief, joining DeMarco Murray who was recently hired as the team's running backs coach.
While OU fans will miss his disruptive presence on the field, there’s no denying that Thomas leaves as one of the most impactful pass rushers in recent Oklahoma history.
Over his four seasons in Norman, R Mason Thomas developed into one of the premier edge defenders in college football. He wasn’t just a flash-in-the-pan talent, he was a consistent force who racked up sacks, tackles for loss, and quarterback pressures that altered games.
His relentless motor, explosive first step, and ability to bend around offensive tackles made him a nightmare matchup for Big 12 and SEC opponents alike.
Thomas’s production spoke volumes: he finished among the conference leaders in key pass-rush metrics, proving he could dominate both in conference play and against top-tier competition.
What stood out most was his ability to finish plays.
Many edge rushers generate pressure, but Thomas converted that pressure into negative plays with remarkable frequency.
Beyond the stats, Thomas played a pivotal role in establishing Brent Venables’ defensive philosophy at Oklahoma.
When Venables arrived in Norman, he brought a hard-nosed, attacking style that blended 3-4 and 4-3 principles with an emphasis on disruption at the point of attack. Thomas quickly became the face of that identity.
His versatility allowed the Sooners to mix fronts, confuse offensive lines, and create chaos in the backfield. Whether setting the edge against the run or exploding off the ball on passing downs, Thomas embodied the “attack, disrupt, and swarm” mentality that Venables sought to instill.
Younger defensive players looked to him as a leader, watching how he prepared, how he practiced with intensity, and how he held himself accountable.
In many ways, Thomas helped lay the foundation for what OU’s defense could become under Venables, turning a rebuilding unit into one known for its aggression and physicality.
Thomas’s journey at Oklahoma wasn’t without challenges.
He arrived as a highly touted prospect but had to earn every snap through hard work and film study. His growth from rotational player to star edge rusher showcased the player development culture in Norman.
Coaches praised his football IQ, his willingness to learn multiple positions along the front, and his ability to adapt to different schemes as the defense evolved.
That experience in Venables’ complex system prepared him exceptionally well for the NFL, where scheme versatility and high football character are prized.Of course, evaluators have noted one potential knock on Thomas: his size.
At approximately 6'2" and 241 pounds with shorter arms, he is undersized for a traditional NFL edge defender. Some scouts worried he might struggle to hold the point of attack against massive offensive tackles in the run game or get overpowered in certain one-on-one matchups.
Yet those concerns often overlook how Thomas plays the game. He wins with leverage, quickness, quick hands, and superior technique rather than raw power.
His ability to slip blocks and use his twitchiness to create angles has allowed him to succeed against much larger opponents throughout his college career.
In today’s NFL, where speed and bend often trump size at the edge position, Thomas’s skill set aligns perfectly with modern pass-rush demands. Players of similar builds have thrived when they play with his kind of effort and technical precision.
For Oklahoma fans and coaches, seeing Thomas drafted represents validation of the program’s ability to develop talent under Venables. The Sooners have produced NFL-caliber defenders before, but Thomas stands out as a prime example of a player who maximized his time in Norman.
His departure leaves a void in the edge group, but it also creates opportunities for the next wave of pass rushers to step up and carry forward the aggressive identity he helped build.
The move to the Kansas City Chiefs is a strong landing spot for Thomas. Kansas City has long valued versatile, high-motor edge players who can contribute immediately in sub-packages.
With Patrick Mahomes leading the offense, the Chiefs are perennial contenders, and adding a player like Thomas gives them a much-needed boost to their pass rush.
For Thomas himself, it’s the realization of a lifelong dream, going from Norman to Arrowhead, where he can continue proving doubters wrong about his size and impact.
As the 2026 NFL season approaches, Oklahoma Sooners supporters will undoubtedly tune in to watch one of their own make an impact at the next level.
R Mason Thomas’s selection is more than just a draft pick; it’s a testament to his hard work, the coaching staff’s vision, and the enduring talent pipeline from Norman to the NFL.
Though OU loses a cornerstone defender, the Sooner Nation can take pride in knowing that one of the best pass rushers in college football is now taking his talents to the
