Isaiah Cook, Idaho State S: the 2026 season story
Isaiah Cook is a sophomore defensive back for Idaho State (Big Sky). He ranks 1331st of 1,841 defensive backs in Division I by the Player Index, which judges every defensive back on the measures that matter at the position, adjusted for the opponents he faced.
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. Isaiah Cook's strongest measure is passes defended per game at 0.32, 383rd of 921 (the average is 0.31). His weakest is interceptions per game at 0.00, 397th of 921 (the average is 0.08).
Season production
Why it matters. Volume is the first sign of how much a coaching staff trusts a player. His tackles per game, 1.7, ranks 900th 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 2nd percentile for volume, 30th for efficiency and 30th 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 8 games, Isaiah Cook's best came in week 8 against Portland State and his quietest in week 4 at Southern Utah.
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. Isaiah Cook is 595th of 920 FCS defensive backs and 61st of 91 in the Big Sky. Next up nationally is Zavian Dilworth of Nicholls, 0.00 ahead on the index.
Defensive backs like him
Why it matters. Players with similar profiles tend to be used the same way, which makes them a quick way to picture his game. His closest match this season is Ricardo Butler of Alcorn State.
