Tomuhini 'Tom Tom' Topui is an elite interior defensive lineman and one of the top trench prospects in the 2026 class, carrying a 0.9485 composite rating and a national top-100/top-10-DL profile out of powerhouse Mater Dei. A 6-3, 320-pound nose/3-technique with a rare blend of mass, raw power, and short-area quickness, he projects as an immediate-impact run-stuffer with disruptive interior pass-rush upside. Heavily recruited nationally (Alabama, Georgia, Ohio State, Michigan, Oregon, USC among many), he signed with USC after a high-profile recruitment.

Physical Profile

Topui carries 320 pounds on a thick, naturally leveraged 6-3 frame with the lower-body anchor and core strength to hold ground against double teams — exactly the build interior schemes covet. His mass is functional rather than soft: he flashes legitimate first-step quickness and lateral agility uncommon at his weight, letting him cross a blocker's face and penetrate gaps. The one measurable that caps his ceiling is arm length — he is not exceptionally long, which limits his ability to lock out and disengage from longer NFL-caliber tackles, so his game leans on hand power and leverage rather than reach.

Play Style

On film Topui is a violent, leverage-driven interior force who collapses the pocket from the inside and resets the line of scrimmage in the run game. He fires off low, stacks and sheds with heavy hands, and consistently demands a double team — when single-blocked he penetrates and blows up gaps. His best reps (the Kahuku isolation film) show him splitting double teams, knifing into the backfield, and chasing laterally with effort that belies his mass. He's a disruptor first whose presence dictates how offenses have to slide protection.

Strengths

  • Elite play strength and heavy hands — produced 19.5 TFL and 9 sacks across his junior/senior seasons and can absorb and split double teams while still generating push, the trait that earned him a top-10-DL national ranking
  • Rare quickness-for-size — wins with both power and a surprisingly explosive first step, giving him a dual rush profile (bull-rush and gap penetration) at 320 pounds against the elite competition of the Trinity League and national schedule
  • Outstanding pad level and leverage with a non-stop motor — plays low to win the leverage battle and consistently finishes/chases, exactly what analysts (Greg Biggins) flagged as separating him from other big-bodied DTs

Areas to Improve

  • Pass-rush plan and counter development — at the HS level he wins on raw power and quickness; he needs a refined hand-fighting arsenal (swim/club-rip counters) to win consistently against college interior linemen who can match his strength
  • Conditioning and snap-count stamina at 320 — to be a true three-down disruptor rather than a rotational early-down anchor, he'll need to manage weight/body composition and sustain his motor over longer drives at the college pace

College Projection

Plug-and-play interior anchor with realistic early-rotation snaps as a true freshman and a path to a starting nose/3-tech role by year two. His floor is a dominant two-down run-plugger who eats blocks for linebackers; his ceiling is a three-down interior disruptor once his pass-rush counters mature. Expect a one-to-two year ramp to full-time starter on a College Football Playoff-level front.

NFL Outlook

Legitimate Day 1-2 draft trajectory if development tracks with the projection. The size-power-quickness combination is an NFL interior-defender blueprint, and his ability to anchor against doubles is pro-translatable. The arm-length limitation and pass-rush polish are the swing factors between a high pick and a sturdy rotational interior pro; if the rush counters and conditioning come along, he profiles as an early-round nose/3-tech.

Best Fit

A multiple/odd-front defense that can deploy him as a 0/1-technique nose to two-gap and command doubles on early downs, while kicking him to a penetrating 3-technique in obvious passing situations. Maximized by a staff with strong interior DL development and a deep rotation that keeps him fresh at 320 — a program built to win in the trenches that lets his power-plus-quickness profile attack gaps rather than just hold ground.

Player Comparison
