As Aaron Glenn continues to elevate the Detroit Lions’ defense, speculation grows that he could land a head coaching role elsewhere. If that happens, the Lions may already have a potential replacement in mind: Dennis Allen, the former head coach of the New Orleans Saints.

Dennis Allen’s Track Record as a Defensive Coordinator

Dennis Allen was let go as the head coach of the New Orleans Saints after a rough 2-7 start to the 2023 season. However, his reputation as a defensive strategist remains solid. From 2015 to 2021, Allen served as the Saints’ defensive coordinator, turning their defense into one of the NFL’s most formidable units.

Under his leadership, the Saints’ defense made a remarkable turnaround, improving from one of the league’s worst to a top-tier group. In 2020, Allen’s defense ranked 5th in points allowed and 4th in yards allowed, a stark contrast to their 31st and 27th rankings when he initially took over.

Allen’s Leadership and Defensive Success

Though Allen’s tenure as head coach of the Saints was less impressive, with a 26-53 record over parts of six seasons, his defensive acumen remained unquestionable. Even during his final two years (2022 and 2023), New Orleans managed to maintain a top-10 scoring defense despite offensive challenges, showcasing his ability to adapt and maintain a strong defense in difficult circumstances.

Dennis Allen’s Connection to Dan Campbell

A key reason why Allen could be a strong fit for the Lions is his relationship with Dan Campbell. The two worked together in New Orleans, with Campbell serving as assistant head coach and Allen running the defense. Campbell’s familiarity with Allen’s defensive system could make him an ideal candidate to replace Glenn if he were to move on to a head coaching role.

What Allen Could Bring to the Lions

If Glenn is pursued for a head coaching position, the Lions will need someone capable of continuing to strengthen their defense. Allen’s success in New Orleans, where he turned a struggling defense into one of the best in the league, makes him a prime candidate. His leadership and defensive expertise could help the Lions build on the foundation Glenn has created and keep their defense among the league’s elite.

A Strong Contender for the Lions’ Future

With his proven track record, connection to Dan Campbell, and expertise in building top-tier defenses, Dennis Allen could be the next defensive coordinator to take the Detroit Lions’ defense to new heights. As the Lions look ahead to a promising future, Allen’s name will likely be one to watch should Glenn depart for another opportunity.
