Jamarion Keyes, Troy S: the 2026 season story
Jamarion Keyes is a junior defensive back for Troy (Sun Belt). He ranks 1131st 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. Jamarion Keyes's strongest measure is yards per catch on his record at 8.5, 159th of 921 (the average is 11.6). His weakest is passes defended per game at 0.00, 795th of 921 (the average is 0.31).
Season production
Why it matters. Volume is the first sign of how much a coaching staff trusts a player. His tackles per game, 3.6, ranks 415th 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 55th percentile for volume, 47th for efficiency and 33rd 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 9 games, Jamarion Keyes's best came in week 4 at Utah State and his quietest in week 2 against Alabama 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. Jamarion Keyes is 667th of 921 FBS defensive backs and 76th of 102 in the Sun Belt. Next up nationally is Bobby Arnold of Utah State, 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 Ian Foster of Memphis.
