Jackie Marshall

Marshall projects as an undrafted free agent prospect with developmental upside as a rotational defensive lineman at the next level. His game tape reveals a high-motor, gap-conscious defender with adequate size (6025, 285 lbs) who consistently wins leverage battles through pad placement rather than elite athleticism. NFL evaluators will view him as a camp body with potential in a 4-3 scheme, though his limited explosion and average lateral agility suggest a ceiling as a backup or special teams contributor.

The 53-grade composite reflects significant athletic limitations—his 40-time and vertical jump metrics trail Day 2/3 standards, raising durability concerns when matched against NFL-caliber offensive linemen. Limited tape against elite competition from the Big 12 creates uncertainty about translational ability, and his production uptick came primarily against lower-tier conference competition, suggesting ceiling questions regarding functional NFL performance.
