Jeff Marks
Wins the gap play after play. The four seasons span two programs and two head coaches: Jeff Brohm and Rich Rodriguez. The first career honor came in 2023: All-Conference USA. One game to point at: 6 tackles and 1 tackle for loss against New Mexico State — Week 13, 2023.
Play style
Stout at the point of attack — steady tackle-for-loss production without a standout pass-rush number.

What the box score actually says
36 tackles. 0 passes defended. 0 interceptions. 4.5 TFL.
Counts only, never a rate — splash-event sample sizes this small (interceptions, pass breakups, TFL) are noise as a rate and signal only as a tally.
