Delby Lemieux is an offensive lineman and 2026 NFL Draft prospect who played his entire collegiate career with the Dartmouth Big Green. A native of Duxbury, Massachusetts, Lemieux attended high school locally and joined Dartmouth as an unranked recruit in the 2022 class, one of the few offensive linemen in this draft class to have remained at one school for his entire career. He developed into one of the top offensive linemen in the FCS over his four seasons, earning three All-Ivy League selections and back-to-back All-American honors, becoming a team captain in his final year. He was a three-year starter at left tackle, finishing his career with 35 games played and 27 career starts while allowing just three sacks across 950 pass-blocking snaps and posting an 84.6 overall PFF grade in 2025, the 10th-best mark among all FCS tackles. He earned an invitation to the 2026 Panini Senior Bowl, where he worked primarily at center, a position he had never played in college, and impressed evaluators with his athleticism and technique at the new spot. He would be the first Dartmouth player drafted since 2004 and the first Dartmouth offensive lineman drafted in the FCS era.
Standing 6-foot-4 and 295 pounds, Lemieux is known for his initial quickness and upper-body strength that allow him to create movement on angle-drive blocks, solid lower-body power, and the football intelligence and communication skills that allowed him to absorb a position change to center at the Senior Bowl with minimal adjustment. NFL evaluators project him as a player who will transition to the interior at the next level, where his technique, athleticism, and natural instincts project him as a developmental center or guard with starter upside in a zone-blocking system.
