Tomuhini Topui

Physical Profile

Listed at 6-3, 320 lbs. Taller than 37% and heavier than 91% of 2026 Defensive Line prospects in the SEC Scouts database (227 with a listed size).

Play Style

He's a penetrating, power-based interior lineman who plays with a low center of gravity. He fires out of his stance, gets under the blocker's pads, and either knocks the blocker back or slips through the gap. Against the run he holds up doubles and frees the linebackers, and he has enough range to make plays down the line from a shaded alignment. As a pass rusher right now he mostly wins with bull-rush power and quickness through a gap, not with polished hand moves. That shows in a production profile heavy on disruption (9 TFL, 2 forced fumbles, 2 QB hurries, 3 pass breakups) rather than sacks. The motor stands out on film for his size, and his snaps in the jumbo backfield show a comfort in space that most 320-pound players don't have.

Strengths

• First-step quickness and gap penetration: USC's staff singled out his get-off and ability to shoot gaps in spring ball. Combined with his low pad level, that lets him get into the backfield before blocks develop. As a senior he had 9 tackles for loss.
• Point-of-attack power: 247 says he can overwhelm single blocks and even disrupt double teams. His shot put and discus marks back up that lower-body and core strength. As a run-down anchor, he's ready for the Power Four level from day one.
• Scheme versatility: Mater Dei moved him between edge, nose guard and 3-technique against a national-level schedule (including Kahuku). That gives coordinators flexibility in both odd and even fronts, on early downs and in sub-packages.
• Proven against elite competition: he was the defensive anchor for a 13-0 CIF Open Division state champion, beat De La Salle in the title game, and was named Trinity League MVP. That's one of the toughest leagues in the country, and a team captain as a senior.

Areas to Improve

• Body control and lower-body flexibility: 247's evaluation flags these. He needs to keep his balance through contact and bend on twists and stunts so he doesn't get washed down when he over-penetrates.
• Pass-rush production and plan: he had 2.5 sacks as a senior, compared with 9 TFL, so right now he's a disruptor more than a finisher. He needs a counter move (swim or push-pull after the initial bull rush) and better hand timing to turn pressures into sacks against college guards.
• Weight management and conditioning: he's gone from about 315 to 325. Keeping that mass without losing his first-step burst, and building the stamina to play more than 25-30 snaps a game, will decide whether he becomes an every-down player.

College Projection

He enrolled early at USC in spring 2026 and made an impression in camp. He's now part of the interior rotation with five-star Jaimeon Winfield and transfer depth, and has 1 tackle through late September. The realistic path is a rotational role in 2026 (early-down run defense and short-yardage packages), a significant rotation role in 2027, and a starting job at nose or 3-technique by 2028. By then his conditioning should support a larger snap count and his pass-rush plan should have matured. If his body composition holds and the counter moves develop, he could reach all-Big Ten level as an upperclassman.

NFL Outlook

247's Gabe Brooks projects him in rounds 2-3. That fits the profile: an explosive, powerful interior lineman with verified strength and versatility. Scouts will question his height and arm length, and he'll need real college pass-rush production to move up draft boards, because shorter defensive tackles who only stop the run usually go on Day 3. If he adds 5-7 sacks a season as an upperclassman while keeping his run-defense value, a Day 2 selection is realistic. His floor is a rotational NFL nose tackle.

Best Fit

A one-gap, attacking front (4-3 under or a multiple Big Ten front) that lets him get upfield as a 3-technique or shaded nose, rather than asking him to two-gap and absorb blocks all game. USC is a natural fit: it's close to home, the staff emphasizes gap penetration, and the rotation lets him develop without carrying a full workload as a freshman. A deep defensive line rotation that manages his snaps will get the most out of his burst.
