While the Miami Dolphins have been plucking away parts of the Green Bay Packers throughout the last couple of weeks, it was uncertain what the role of former Packers linebackers coach Sean Duggan would be for Jeff Hafley’s new staff. On Sunday, ESPN’s Jeremy Fowler reported that Duggan, who was co-defensive coordinator for Hafley for one season at Boston College, will be Hafley’s non-play-calling defensive coordinator in Miami. Hafley has previously stated that he will call plays from the sideline,
on top of his head coaching duties, after calling plays from the box in Green Bay.
Duggan and Jacksonville Jaguars linebackers coach Tem Lukabu were always linked to the Dolphins’ defensive coordinator job. Lukabu was Hafley’s first defensive coordinator at Boston College, serving three seasons as the team’s sole defensive coordinator from 2020 to 2022. When Lukabu left for the NFL in 2023, Duggan and Aazaar Adbul-Rahim split defensive coordinator duties under Hafley. Abdul-Rahim is currently the co-defensive coordinator and defensive backs coach at the University of Maryland.
If you’re trying to keep track of the Packers’ coaching staff moves, here’s what’s happened this offseason, so far:
