Mercyhurst’s Mark Harrington Jr. is a rising sophomore LB with size, instincts, and special-teams value
In the 2025 season, Mark Harrington Jr. flashed as a true freshman for Mercyhurst, posting 4 total tackles, including 3 solo stops, in limited action. Listed at 6-foot-2 and 230 pounds, he brings an SEC-ish linebacker build to a developing Mercyhurst defense, and the staff clearly trusted him enough to get him on the field early. The bigger sell isn’t just the stat line: he profiles as a physical, disciplined, team-first defender with upside in pursuit and tackling—exactly the kind of player who can earn more snaps fast if his processing keeps climbing.
