GREEN BAY – The Packers have promoted defensive assistant Sean Duggan to linebackers coach.
Here are five things to know about Duggan:
- He came to the Packers last year from Boston College with defensive coordinator Jeff Hafley.
During Hafley's four-year stint as the head coach at Boston College, Duggan was his linebackers coach for the entire tenure, adding co-defensive coordinator duties in 2023.
- He was reunited with one of his proteges in Green Bay.
While at BC, Duggan coached Packers LB Isaiah McDuffie for the final season of his college career in 2020, which was also McDuffie's best – 107 tackles and second-team All-Atlantic Coast Conference honors – before the Packers drafted him in the sixth round in 2021.
- Duggan and Hafley first worked together at Ohio State.
Before becoming Boston College's head coach, Hafley spent one season as co-defensive coordinator and defensive backs coach at Ohio State in 2019. Duggan worked on that Ohio State staff as a graduate assistant, his fourth different stop in the college coaching ranks, and he's been with Hafley ever since.
- He also played at Boston College and began his coaching career there.
A Cincinnati native, the 31-year-old Duggan played four years at BC (2011-14), appearing in 45 career games and being voted team captain as a senior.
After his playing days, Duggan began his coaching career at BC in 2015 as a graduate assistant before moving on to coach linebackers at Hawaii (2016-17) and UMass (2018).
- He was both high school and college teammates with Pro Football Hall of Fame finalist Luke Kuechly.
Duggan's first two years of high school at St. Xavier in Cincinnati overlapped with Kuechly's last two, and the pair were at Boston College together in 2011 – Duggan's freshman year and Kuechly's last collegiate season before being drafted in the first round by Carolina in 2012.
