"Twitchy, hand-active SEC edge who stacked 17 career sacks and a 9-sack breakout junior year — the swipe/chop counter package is what pushed him into Day 2."Pre-draft read
He aligns as a sub-package speed-to-power edge, excelling with quick get-off and a layered hand plan. He consistently wins the first step and employs a varied arsenal—swipe, chop, cross-chop, long-arm—keeping offensive linemen guessing. He sets a firm edge in the run game using active hands and good pad level but can be sealed inside when too high.
He chases the football sideline-to-sideline, demonstrating high effort. His most significant contributions come in evident pass-rush situations, often rotating inside on twists and games, targeting the B-gap. He bends sufficiently to corner the arc against average tackles, but his true value lies in his counter moves when his initial rush stalls, maintaining pressure.
Kansas City Chiefs operate a multiple front defense using both true 3-4 and 4-3 principles, but with a focus on pass rush and an attacking front to create pressure on quarterbacks.
Immediate sub-package pass rusher on obvious passing downs as a rookie, with a ceiling to develop into a starting 4-3 defensive end or 3-4 rush linebacker who excels at generating pressure.
A more static, two-gap 3-4 defensive end system would significantly diminish his impact due to his size and play style, as he thrives with a penetrating rush.
His high-motor, penetrating pass-rush style and strong hand technique make him a good fit for a defense that values disruption and a diverse pass-rush plan, despite his average length.

R Mason Thomas — Career Oklahoma Highlights (2022–2025)
Four-year Oklahoma cutup — freshman rotation to 9-sack SEC-era breakout, showcasing the hand plan, counter package and interior rush on games.
This prospect projects as a sub-package edge rusher with the potential to develop into a base end. His pro-ready hand technique and refined pass-rush plan allow him to consistently generate pressure, particularly when his initial rush is challenged. While his frame is more compact and his testing numbers did not elevate his profile, his on-field execution against high-level competition indicates a clear path to early contributions.
He developed over four years at Oklahoma, with a significant breakout in his junior season in the SEC. This progression, along with consistent performance against SEC tackles, highlighted his technical proficiency and led evaluators to focus on his refined hand usage and diverse counter moves. Despite a slightly less productive senior year in terms of sacks, his improved run defense and expanded rush repertoire maintained his strong film grade.
Concerns among evaluators primarily centered on his length and a testing profile that did not fully resolve questions about his athletic ceiling, tempering his ultimate projection for some teams. He settled into a consensus as a top-40 rusher, prized for his technique and plan over elite physical traits, ultimately being drafted 40th overall.
- 01
Elite first-step quickness
Off-the-ball get-off is the trait tape opens with; consistently wins the corner rep against SEC tackles when he times the snap and gets vertical.
- 02
Layered pass-rush plan
Rare college prospect who shows a full menu (swipe, chop, cross-chop, long-arm punch) rather than one signature move, with real counters when the initial rush stalls.
- 03
Hand technique and violence
Fires his hands early to defeat tackle punch, keeps them inside the frame and finishes with a rip; hand fighting is his primary separator on tape.
- 04
Interior rush on stunts and games
Comfortable flipping inside as a sub-package B-gap rusher, which multiplies value for defenses that live in NASCAR fronts and games.
- 05
SEC production and durability
17.0 career sacks and 25.5 TFL against a Big 12/SEC schedule; played all 42 games across four seasons with no significant lost-time injuries.
- 01
Length and frame
Around 6-3/253 with average arm length; NFL tackles with 34"+ arms can lock him out before his counter package activates.
- 02
Testing profile
Held back at the Combine and did not run publicly at his Pro Day, leaving the athletic ceiling unresolved for teams that weight testing heavily.
- 03
Bend limitations
Corners the arc well against average tackles but stiffens up as a true speed-to-power rusher against pro-caliber sets; not an elite dip-and-rip finisher.
- 04
Anchor vs. down blocks
Can get top-heavy and sealed inside when tight ends or tackles combo him down; the run-defense reps are competent, not dominant.

A dash means the figure is not published by a source we trust — never a zero we invented.
Sub-package rush specialist who flips inside on games and lives on third downs; role fit for a Spagnuolo front and a reasonable Year 2-3 projection for Thomas.
Undersized speed rusher who leaned on a defined hand plan and inside counter to become a double-digit-sack producer without elite length; realistic top-end outcome if the counter package scales.
Hand-technique rusher whose frame and length limits capped him as a rotational contributor; the outcome if NFL tackle length swallows the counter game.
Everything above is the pre-draft evaluation. This section is what actually happened — updated year over year.
**Pre-draft context.** A four-year Oklahoma developmental story who did his real growing in the weight room and the film room before the box score ever caught up. Rotational as a freshman and sophomore, he took over as the Sooners' primary rush end in 2024 and delivered a 9-sack, 12.5-TFL breakout in the program's first SEC season — a stretch that pushed him from Day 3 flier to Day 2 name. A slightly quieter senior year (6.5 sacks in 10 games) came alongside cleaner run tape and a wider counter package, which is what evaluators kept circling. The scouting label was consistent: pro-ready hands, real plan, question marks on the length and top-end explosion.
**NFL fit — Kansas City Chiefs.** Kansas City passed on first-round edge names (they had reportedly floated Rueben Bain Jr. as a Round 1 fallback) and instead used the 40th overall pick on a rush-first sub-package piece behind the established interior/edge rushers. Kansas City has always leaned on rushers who can flip inside on stunts and games, which fits Thomas' skill set; the immediate ask is third-down snaps, pass-rush games out of the B-gap and rotation at strong-side end. Signed his rookie deal on May 21, so he arrives on schedule with training camp reps as an early-down rotational piece and a passing-down rusher.
**Retrospective.** Too early to grade — the tape and pedigree suggest a rotational Day 2 rusher who should carve out a real sub-package role by year two, with Pro Bowl outcomes gated by whether his frame holds up against NFL tackle length. If the hand plan translates the way it did in the SEC, the pick reads as a clean value at 40; if he tops out as a situational rusher, it still profiles as a fair second-round outcome for Kansas City given how they use their D-line.
