Jackie Marshall is a versatile, high-effort defensive lineman who brings a tweener profile with experience aligning across the front, including 1-tech, 2i, 3-tech, and 5-tech. At Baylor, he functioned primarily as a structure-based defender, logging significant snaps within the rotation and contributing through effort, physicality, and assignment discipline. On tape, Marshall showed flashes of athletic ability and lateral movement, paired with a quick first step that allowed him to be effective in slanting and movement-based fronts. His ability to play square, disrupt pullers, and maintain gap integrity highlights his value as a run defender within structure.
Marshall’s athletic profile stands out, supported by testing numbers with a 4.88 40 time, 1.69 10 yard split, and 4.68 shuttle, and visible twitch on tape, particularly when working laterally. He plays with a decent motor and competitive toughness, showing urgency in key situations and the ability to contribute as a communicator along the defensive line. However, his game is more reactionary than instinctive, as he can be slow to process concepts beyond initial blocking keys, particularly against play action or misdirection, which limits his ability to consistently access his physical tools.
As a pass rusher, Marshall’s production does not match his flashes. He operates primarily as an effort-based rusher, showing a developing toolbox but lacking a defined plan, consistent counters, or a reliable go-to move. While he can generate initial pop on speed-to-power attempts, he struggles to sustain push due to inconsistent lower body drive and will often stall out once engaged. His tendency to get stuck on blocks and lose track of sequencing further limits his effectiveness, preventing him from becoming a consistent disruptive presence.
In the run game, Marshall is at his best operating as a gap-control defender, showing the ability to hold position, play with physicality, and disrupt pullers and insert blockers at a high level. He displays good surf technique and can handle double teams when playing with proper leverage, though inconsistencies in pad level and a tendency to drop his head at the point of attack can lead to loss of control. While he is generally difficult to reach due to his athleticism and inside hand consistency and plays with solid effort, his ability to disengage and finish plays remains inconsistent, with tackling angles and overall finishing ability needing refinement.
The Big Picture:
Jackie Marshall is a tweener, movement-based defensive lineman who wins with athletic ability, effort, and alignment versatility rather than consistent disruption or refined pass rush ability. He flashes quickness, lateral mobility, and a developing toolbox, but struggles to translate those traits into consistent on-field impact due to processing delays, and lack of pass rush sequencing. Marshall projects best as a rotational defensive lineman in a movement-based front, where he can be schemed into advantageous situations rather than relied upon to win one-on-one. His athletic profile provides intrigue, but his overall impact, lack of a defined role, and developmental needs create a lower ceiling and a projection dependent on refinement and role clarity.
Scheme and Team Fits:
Marshall projects best in a multiple-front or 4-3, movement-based defensive scheme that emphasizes defensive line movement, versatility, and rotational usage. He is most effective when allowed to operate on angles, slants, and schemed movement, where his quickness and lateral ability can be maximized without requiring consistent one-on-one wins or a fully developed pass rush plan. His experience aligning from 1-tech through 5-tech provides value in sub-packages and rotational roles, particularly in systems that prioritize assignment soundness and front multiplicity.
Pittsburgh Steelers
Pittsburgh presents a strong fit for Marshall as a rotational defensive lineman within a multiple-front system that values physicality and gap discipline. His ability to align across the front and play within structure allows him to contribute as a depth piece, where his effort and versatility can translate without requiring consistent pass rush production.
Baltimore Ravens
Baltimore’s heavy use of defensive line rotation and movement-based fronts aligns well with Marshall’s skill set. His ability to absorb blockers, disrupt insert players, and operate within a gap-controlled system allows him to function as a complementary interior piece who supports linebacker play and contributes through effort and discipline.
San Francisco 49ers
San Francisco’s defense offers a role where Marshall can contribute as a rotational interior defender within a deep and structured defensive line unit. His lateral movement ability and alignment versatility fit a system that uses defensive line depth and scheme to create opportunities, allowing him to operate within structure rather than relying on individual pass rush wins.
NFL Player Comparison:
James Lynch
Marshall mirrors Lynch as a tweener, effort-driven defensive lineman who provides value through alignment versatility, movement ability, and role execution rather than consistent disruption. Both players flash athletic ability and a developing pass rush toolbox, but lack a defined plan, counters, and consistent finishing ability, limiting their overall impact. They project best as rotational depth pieces whose value comes from flexibility and assignment soundness rather than production.
Draft Projection: Late Round 7- UDFA (Day 3)
Marshall projects as a late 7th rounder his tweener profile and lack of a defined position reduce his draft value. While he has shown signs of transitioning toward an edge role with his weight loss for the combine, he currently lacks the pass rush plan, counters, and consistent production to justify a higher selection at that position, especially considering the abundance of better talent in the edge group this year. Even when evaluated within a weaker defensive tackle class, his overall impact does not consistently meet draftable thresholds. His athletic ability provides enough intrigue to warrant a flier, but his developmental curve and need for refinement make him a better candidate to earn a roster spot through either late 7th rounder or post-draft development.
Grade: 3.85
Marshall holds a 4.05 tape grade before the curve, and a 24.30/42 trait grade. A -0.20 curve adjustment brings his final grade down to 3.85, reflecting a player whose athletic traits and flashes are outweighed by inconsistencies in processing, pass rush execution, and overall impact. While he shows good movement ability, effort, and versatility across the front, his marginal mental processing and pass rush limitations prevent him from consistently affecting plays. He projects as a developmental, rotational defensive lineman whose early value will come from effort, alignment flexibility, and role execution rather than disruptive production.
