Tomuhini 'Tom Tom' Topui is a four-star interior defensive lineman (0.9485 composite, top-120 nationally, No. 3 DT per ESPN) out of powerhouse Mater Dei, widely regarded as one of the premier nose tackle prospects in the 2026 cycle. A former Oregon commit who flipped to USC in March 2025, he arrives with rare functional strength, a proven track record against elite national competition, and Trinity League MVP hardware as a junior — an unusual honor for an interior defender.

Physical Profile

Listed at 6-3 and between 295-330 pounds depending on the season, Topui carries a dense, powerful frame purpose-built for the A-gap. He lacks elite length for the position, but compensates with exceptional play strength, natural leverage from his height, and quickness that is rare for a man his size. His lower-body power lets him anchor against double teams without surrendering ground, and his get-off is sudden enough to jar guards and centers at the snap.

Play Style

Topui is a classic zero/one-technique with a modern twist: he wins first with power and leverage, striking blockers at the snap and resetting the line of scrimmage, but he has enough quickness to win with speed on slanted fronts. On film he routinely absorbs double teams without displacement, then sheds late to make plays at the ball. His motor stands out — he pursues laterally and downfield in ways most 300-pounders don't — and there's a visible physical edge and nastiness to his game that shows up in isolation film against top opponents.

Strengths

  • Elite point-of-attack strength — consistently takes on double teams, holds his ground, and still generates push up the field, the defining trait in his 247Sports evaluation
  • Heavy hands and advanced leverage/pad level for a high schooler — can shock and shed offensive linemen at contact rather than just occupying blocks
  • Non-stop motor and genuine nastiness — plays through the whistle against the best competition in the country (Trinity League, marquee matchups like Mater Dei vs. Kahuku), earning Trinity League MVP and MaxPreps Junior First Team All-American honors
  • Positional versatility — dominant enough on the offensive line in camp settings that evaluators note he might be an even better guard prospect, a signal of overall trench athleticism

Areas to Improve

  • Below-average arm length for an interior lineman — must continue refining hand placement and shed technique so longer college guards can't lock him out
  • Pass-rush plan beyond power — developing a reliable counter move and lateral finishing burst will determine whether he's a two-down run-plugger or a three-down disruptor
  • Weight management and conditioning — his listed weight has fluctuated between 295 and 330; finding his optimal playing weight will maximize his snap count

College Projection

Signed with USC (December 2025) and already enrolled as a true freshman. Projects as an immediate rotational nose/defensive tackle in 2026 with the physical maturity to handle 15-25 snaps a game early — interior DL readiness is his calling card. Expect him to push for a starting interior role by year two, with All-Big Ten candidacy realistic by his second or third season if the pass-rush toolkit develops.

NFL Outlook

Legitimate NFL draft trajectory. His anchor strength, leverage, and double-team absorption are translatable NFL nose tackle traits, and interior run-stuffers with his motor carry Day 2 floors. The swing factor is pass-rush production: if he develops interior push and a counter arsenal at USC, he has top-60 potential; if he remains primarily a two-down player, he profiles as a Day 3 pick with a long NFL career as an early-down anchor.

Best Fit

Best maximized as the nose in an odd front or as a one-technique in an aggressive four-down scheme that asks him to eat double teams and free up linebackers — exactly the role USC's defense can offer. Programs with strong development track records for Polynesian interior linemen and heavy Big Ten-style run-game exposure fit his profile perfectly; he is the type of prospect who makes everyone behind him better.
