Southern Miss’s 300-pound interior anchor Kei’shaun Mashburn brings juice, size, and upside to the DL room
Kei’shaun Mashburn is a 2026 junior defensive lineman at Southern Miss listed at 6-foot-2, 300 pounds, and his profile screams interior run-stopper with enough mass to clog gaps and keep blockers honest.[1][2] He transferred from Allen University, where he logged 0.5 sacks, 0.5 tackles for loss, and 10 total tackles in 11 games in the 2025 season, which hints at rotational production rather than headline-grabbing numbers—but the frame and transfer pedigree suggest a developmental upside piece with real trench value.[13] If a team wants a sturdy, physically mature DL who can battle inside and add depth without needing the spotlight, Mashburn is the kind of quietly useful piece that coaches love and offenses notice the hard way.[1][2][13]
