Michigan’s commitment from 4‑star defensive lineman Alister Vallejo out of Liberty Hill HS marks a significant boost for the Wolverines—especially on the defensive front. Here’s what his choice means:
🏈 Boosting the DL Room and National Standing
Vallejo, ranked as a four‑star by 247Sports (though three‑star composite) and the No. 48 DL nationally, adds size (6’3″, 310 lb) and disruptive potential to a Michigan defensive line that consistently develops NFL talent . His commitment has already helped elevate Michigan’s 2026 class to 31st in the nation, underscoring the ripple effect of landing a key front-seven recruit .Continuity in DL Development Pipeline
Michigan has built a reputation for producing pro-caliber defensive tackles—names like Mason Graham and Kenneth Grant come to mind, both first-round NFL picks. Vallejo joins this lineage and signals the program is successfully reloading the interior line . He’ll benefit from top-level coaching and will be groomed for roles on early-downs and rotational packages.

Depth, Competition & Cultural Fit
Depth along the defensive front is crucial, especially in the Big Ten. Vallejo brings competition to the camp and occupies a crucial developmental spot. Plus, he’s versatile—he even lined up on the offensive line in high school, reminiscent of rust-proof, two-way prospects . His early years of strong production (65 tackles/11 sacks in 2023, 47/7 in 2024) show he’s not just size but production-ready .

Program Momentum & Recruiting Traction
Vallejo’s decision to pick Michigan over Kansas and Notre Dame is a recruiting statement. It tells other blue-chip prospects that Michigan is a destination. Landings like this build positive momentum—helping to secure flips (look at previous Underwood/Haywood flips) and attract top-tier talent .

Strategic Outlook under Sherrone Moore
Sherrone Moore is stacking talent quickly: Underwood, Babalola, Haywood, Marshall, and now Vallejo—all signaling a power surge in both offense and defense. Vallejo specifically addresses the defensive tackle spot, helping ensure Michigan won’t be vulnerable inside against big Big Ten offensive lines
In Summary
Vallejo gives Michigan a strong interior defender with immediate upside. His commitment:
Enhances DT depth and rotation;
Offers another ticket in Michigan’s NFL-calibre DL pipeline;
Bolsters a rising recruiting class with national credibility;
Fits into a broader build under Sherrone Moore, showcasing elite recruiting across all fronts.
Expect Vallejo to be a cornerstone in Michigan’s next wave of defensive talent. With more recruits watching, each commitment from a high-upside player like him magifies the program’s upward trajectory.
