Former Boston College linebacker Sean Duggan enters his fourth season as BC’s linebackers coach and first as co-defensive coordinator; a position he was promoted to under head coach Jeff Hafley in February 2023. Duggan, who played in 45 career games during his career with the Eagles, served as captain of the 2014 Boston College squad.

Vinny DePalma ranked 15th in the ACC in tackles in 2022 with a team-high 87. He became the fourth linebacker under Duggan’s tutelage to earn All-ACC recognition as a Honorable Mention pick.

Isaiah Graham-Mobley ranked 28th in the ACC in tackles during the 2021 season, despite missing three games due to injury. He averaged 5.8 tackles per game and signed as a free agent with the Carolina Panthers following the 2022 NFL Draft.

In his first season back at the Heights, Duggan oversaw a unit that featured two of the nation’s leading tacklers.

Isaiah McDuffie led BC and ranked fifth in the nation with 107 tackles in 2020. He ranked 30th nationally with 9.7 tackles per game and was an All-ACC Second Team selection.

The Green Bay Packers selected McDuffie in the sixth round of the 2021 NFL Draft. The Buffalo native had a career-best 16 tackle performance vs. No. 2 Notre Dame, which was tied for second most by an ACC player all season.

Max Richardson earned All-ACC Third Team honors after finishing second on the team and fourth in the ACC with 99 tackles. He ended the year 11th nationally in tackles and posted double-digit tackles in five ACC games. Richardson signed as a free agent with the Las Vegas Raiders following the 2021 NFL Draft.

Duggan joined the defensive staff in February of 2019 and served as a graduate assistant coach for the Buckeyes. He was a key part of an Ohio State defensive staff that ranked first nationally in yards per play (3.9), second nationally in total defense (247.6 yards per game), third nationally in scoring defense (12.5 points per game), third nationally in sacks (3.92 per game), seventh nationally in rushing defense (99.5 yards per game), second nationally in passing yards allowed (148.1 yards per game) and first nationally in red zone defense (64.2%).

Prior to Ohio State, Duggan spent one season at UMass as linebackers coach in 2018. During his stay in Amherst, he mentored Bryton Barr, a New England Football Writers Association (NEFWA) All-Region Team selection. Barr was also the ECAC Defensive Player of the Year.

Duggan served on the University of Hawai’i staff as linebackers coach for the 2016 and 2017 seasons. While at Hawai’i, Duggan guided a host of successful Rainbow Warriors, including 2016 All-Mountain West First Team choice Jahlani Tavai and NFL-bound Jerrol Garcia-Williams.

Duggan joined the BC staff in 2015 as the team’s defensive graduate assistant and helped the unit produce the nation’s top total defense and No. 4 scoring defense (15.3 points/game).

As a player at BC, Duggan played in 45 career games and was a captain in 2014. He was the sixth BC captain from St. Xavier High School in Cincinnati at the Heights, joining Pat Ross (2005), Nick Larkin (2007), Alex Albright (2010), Luke Kuechly (2011) and Ben Glines (2019). Duggan finished his BC career with 115 career tackles, 6.5 TFLs, two interceptions and two fumble recoveries.
