Jadyn Marshall, Cal Poly CB: the 2026 season story

Scouting report
Why it matters. Every measure is set against every ranked defensive back, so a strength here is a strength against the whole position, not just his own team. Jadyn Marshall's strongest measure is passes defended per 100 throws at 1.3, 390th of 921 (the average is 1.3). His weakest is tackles per game at 2.2, 811th of 921 (the average is 3.7).
Season production
Why it matters. Volume is the first sign of how much a coaching staff trusts a player. His tackles per game, 2.2, ranks 811th among 921 ranked defensive backs.
Against every defensive back
Why it matters. Volume, efficiency and impact plays can tell different stories: a player can be busy without being effective, or rarely used but dangerous every time. Among ranked defensive backs he sits, on average, in the 12th percentile for volume, 52nd for efficiency and 57th for impact.
The season, game by game
Why it matters. Consistency matters to a team: one huge game and five quiet ones is a different season from six solid ones. Over 11 games, Jadyn Marshall's best came in week 10 against Northern Arizona and his quietest in week 2 at San José State.
Where he does his damage
Why it matters. The shape of a player's production, not just its size, is what opponents scout.
National and conference
Why it matters. The Player Index puts every defensive back on one scale, adjusted for the defenses or offenses he faced, so a rank here is comparable across conferences. Jadyn Marshall is 351st of 920 FCS defensive backs and 35th of 91 in the Big Sky. Next up nationally is Braylon James of Cornell, 0.01 ahead on the index.
Defensive backs like him
