a depth-defining Duke safety with upside
Marvin Marcelin is a Duke defensive back worth tracking because safeties at his level are often judged less by box-score stats and more by reliability, communication, and range; with Duke’s defense coming off a 2024 season in which the Blue Devils finished 9–4, the fit question is whether he can translate athleticism and assignment discipline into consistent snaps in a competitive ACC secondary.[3][8] The key differentiator to watch is whether he brings steady coverage versatility and special-teams value—traits that usually separate roster filler from trusted depth at safety.
