Alister Vallejo

Physical Profile

Vallejo is 'verifiably big' (247Sports' Gabe Brooks) with a thick, naturally filled-out 6-3/305 frame and the trunk-and-anchor mass you want from an interior defender who has to two-gap against high-major guards. The multi-sport background matters here: his shot put data confirms genuine lower-half explosiveness and hip torque, not just listed weight — that rotational power translates directly to a violent first punch and the ability to generate knockback from a stationary three-point stance. At 6-3 his pad level is naturally lower than taller ends, an asset for winning the leverage battle in the A and B gaps.

Play Style

Vallejo is a disruptive interior penetrator who plays with heavy, active hands and attacks gaps rather than passively reading. On film he shows a strong bull rush that collapses the pocket and a finishing burst that converts pressures into sacks — uncommon for a player aligned over the guard or nose. Against the run he two-gaps with leverage when asked but is at his best shooting a single gap and disrupting in the backfield. The blocked-kick production reflects elite get-off and effort.

Strengths

• Violent, decisive hand usage — the primary engine behind 18 career sacks despite operating from the interior, where pass-rush production is much harder to come by than off the edge; he wins with strike timing and hand placement rather than length
• Elite disruption profile for a defensive tackle: 26 hurries and 5 blocked kicks show he affects the pocket and the kicking game beyond raw sack totals, plus 100+ tackles signals he plays the run sideline-to-sideline, not just a two-down plugger
• Verified explosive athleticism via shot put background — the rotational lower-body power shows up as knockback at the point of attack and a quick, heavy first step off the snap

Areas to Improve

• Length/arm extension at 6-3 — needs to win the hand-fighting battle consistently to avoid getting reached and engulfed by longer FBS interior linemen; must refine a counter (swim/club-arm-over) for when the initial bull or rip is stalemated
• Pad level and conditioning consistency over a full snap count — at 305+ he must keep his weight playable and his motor high into the fourth quarter to be a three-down player rather than a rotational early-down anchor

College Projection

Projects as a developmental-to-rotational interior defender at Michigan with starter upside by his second or third year. He steps into a defensive line room and coaching pedigree (DL coach Lou Esposito) suited to his skill set, where he can redshirt or rotate early to add functional weight and refine hand technique before earning a three-down role as a 3-technique/nose hybrid. His floor is a quality rotational space-eater; his ceiling is a multi-year starter and interior pass-rush asset.

NFL Outlook

As a four-star top-210 national prospect, Vallejo carries legitimate Day 2-3 draft developmental potential if his interior pass-rush production translates to the college level. The combination of violent hands, rotational explosiveness, and rare disruption numbers for a DT is exactly the trait profile NFL evaluators covet in 3-techniques; the swing factors will be length compensation and whether he develops a reliable pass-rush plan against pro-caliber guards.

Best Fit

An aggressive, gap-attacking, one-gap penetration scheme that lets him fire off and disrupt rather than read-and-react two-gap every down — which aligns well with Michigan's interior usage. A program with a strong defensive-line development infrastructure (which he found in Esposito's room) maximizes his hand technique and conditioning, letting his natural explosiveness and finishing ability play as a 3-technique or attacking nose.
