The Miami Dolphins are bringing in Sean Duggan as their new defensive coordinator, according to sources. Duggan will reunite with head coach Jeff Hafley, marking their fourth coaching collaboration. Duggan, who recently served as the Green Bay Packers' linebackers coach, will now lead a Dolphins defense aiming for improvement after a challenging season.

Duggan's appointment comes as the Dolphins look to bolster their defensive performance. Last season, the team ranked 22nd in yards allowed per game. Despite the coordinator change, Hafley will be calling the defensive plays. The Dolphins' defense includes key players such as Zach Sieler, Minkah Fitzpatrick, and Bradley Chubb.

This move signifies a shift in the Dolphins' defensive strategy under Hafley's leadership. Duggan's experience at the collegiate and professional levels, particularly his time with Hafley at multiple institutions, adds a layer of familiarity. The focus will be on elevating the defense's performance and impact on the field.

With Hafley calling plays, the Dolphins are banking on a cohesive approach. Duggan's role will be pivotal in implementing defensive schemes and strategies. The team's goal is to become more competitive in the upcoming season. Fans will be watching closely to see how this transition influences the team's success.
