Jax Tanner

Physical Profile

Listed at 6-4/275-285 but measured closer to 6-2.5, 287 with 34-inch arms — and that combination is better for him than the listed height would be. Sub-6-3 height with 34-inch reach is a genuinely advantageous build inside: natural leverage under a defensive tackle's pads, plus enough length to reset hands and recover when a 3-technique wins first contact, which is the exact trait short guards usually lack. Frame is already close to college playing weight rather than needing a two-year mass build, and the mass is functional rather than soft. He is a guard/center body, not a tackle body — the arm length is elite for the interior and merely adequate on an edge, and there is no long-speed or hip-flip evidence to suggest kicking him outside.

Play Style

A phone-booth mauler. He plays with his weight on the balls of his feet, gets under pads on the snap, and looks to displace rather than stalemate — the pancake total is the byproduct of a player who treats every run rep as a chance to put someone on the ground. In protection he anchors rather than catches, sitting down on power and using the long arms to keep rushers off his frame; the zero-sack season suggests his hands land inside and his base doesn't collapse under the bull. He is at his best in gap and duo concepts where he can fire off downhill into a defined target, and least comfortable when asked to cover ground horizontally and win with feet instead of pop.

Strengths

• Finishing temperament backed by real volume — 115-plus documented pancakes in a single junior season is not a highlight-reel accident, it is a player who blocks through the whistle on down-after-down run concepts and takes defenders to the ground rather than sustaining and letting go
• Pass-protection reliability: zero sacks surrendered across the 2024 season, which for an interior lineman means he handled both the bull rush and the interior twist/stunt games without giving up the pocket's inside edge — the specific failure that gets quarterbacks hit
• Leverage-plus-length profile (roughly 6-2.5 with 34-inch arms) that lets him win the first-contact point on down blocks and combos while still having the reach to redirect a rusher who beats his initial set
• Evaluated up, not down, by the people who saw him live — Idaho Gatorade Player of the Year and a Navy All-American Bowl invitation, and a P4 offer sheet spanning the SEC, Big Ten and Big 12 that says national-level staffs graded him above his composite number

Areas to Improve

• Competition-level calibration is the honest caveat. Idaho 5A does not produce weekly reps against 6-4/290 four-star defensive tackles, so the pancake volume partly reflects a physical-mismatch environment. His true grade against P4-caliber interior length is largely unproven, and the All-American Bowl week is the only genuine apples-to-apples sample on tape
• Lateral range and second-level efficiency need work for a modern zone-heavy scheme. The profile reads as a leverage-and-power winner at the point of attack more than a lineman who redirects on the move; climbing to fit a linebacker in space and hitting reach blocks on wide-zone tracks are the reps to attack
• Two-year layoff management. A mission means no organized football from spring 2026 to roughly 2028 — pad level, hand timing and pass-set footwork are all perishable, and the re-acclimation period is the single biggest variable on his projection

College Projection

Signed to BYU with an expected 2028 arrival following a mission, which reshapes the timeline meaningfully: he will report as a physically mature 21-year-old already at or above college playing weight, but with two years of rust and a 2028 offensive line room that BYU has stocked heavily (Alai Kalaniuvalu, Bott Mulitalo, Austin Pay in the same pipeline). Realistic path is one year of re-acclimation and technique rebuild in 2028, competition for a guard spot in 2029, and multi-year starter status from there — BYU's returned-missionary development infrastructure is the best in the country at exactly this, which is a real part of why he chose them. His body is essentially finished, so the development budget goes entirely to footwork, pass-set consistency and scheme install rather than to weight-room mass.

NFL Outlook

Draftable ceiling exists but is back-loaded and unusually far out. A 0.8933-composite interior lineman who becomes a multi-year P4 starter lands in the Day 3 / priority free agent band historically, and 34-inch arms at a leverage-friendly height is the kind of measurable that survives a combine and keeps him on boards. The mission timeline pushes any evaluation to roughly 2031-2032, by which point age becomes a factor — he would enter the league at 24-25, which narrows the developmental-project lane and means he needs to be a finished, plug-and-play guard or center, not a projection. Verdict: legitimate NFL-caliber build, but the draft outcome hinges almost entirely on whether he shows he can move laterally at P4 speed post-mission.

Best Fit

A gap/power-based run scheme that lets him fire off downhill — duo, counter, inside zone with vertical double-teams — rather than an outside-zone system that would ask him to run and reach in space every snap. He also fits best in a program that specifically develops returned missionaries and has the patience for a redshirt-plus-reacclimation runway, which is exactly what BYU offers and why the fit is genuinely strong rather than just a legacy pick (father Mike Tanner was a BYU linebacker from 2000-2003; brother Gage is also in the program). Center is a position worth testing him at in year one — the height, arm length, leverage and pre-snap demeanor all point that direction, and it would raise his floor considerably.
