Former Oklahoma Defensive End R Mason Thomas Picked on NFL Draft’s Second Day

The Kansas City Chiefs selected Oklahoma defensive end R Mason Thomas with the No. 40 pick in the 2026 NFL Draft, adding a high-ceiling pass rusher to a defense that continues to reload rather than rebuild.

Thomas became a star during his final two seasons at Oklahoma, registering 25.5 tackles for loss and 17 sacks over four years in Norman. His breakout 2024 season — 12.5 tackles for loss and nine sacks — earned him Second Team All-Big 12 honors and put him firmly on NFL draft boards.

The Chiefs' selection reflects a continued commitment to edge pressure, which has been the cornerstone of Steve Spagnuolo's defensive scheme. Thomas brings explosiveness off the edge and a developing repertoire of pass-rush moves that should translate well to the NFL level.

At 6'3" and 250 pounds, Thomas is slightly undersized for a traditional defensive end, but his burst and bend around the corner are exactly what modern NFL defenses look for in edge rushers. The Chiefs have a history of maximizing undersized speed rushers in their system.

Thomas joins a Chiefs team coming off another deep playoff run, with a defensive front that rotates heavily. The rotational system should allow him to contribute in passing situations immediately while developing his run defense against NFL-caliber offensive linemen.

**What This Means For You:** For Chiefs fans, Thomas is a classic Spagnuolo pick — speed over size, disruption over containment. He'll have every opportunity to earn rotational snaps as a rookie. For fantasy managers in IDP leagues, Thomas has sack upside but will need a year or two before he's a reliable weekly starter. The Chiefs' development track record with edge rushers is strong, which makes this pick higher floor than most second-round defensive ends.
