The Jets’ search for a new defensive coordinator is over. The team is hiring Brian Duker per Tom Pelissero.
The 36 year old Duker worked under Glenn with the Lions for three years. He went from defensive assistant in 2021 to safeties coach in 2022 to defensive backs coach in 2023.
The last two years he worked as the pass game coordinator and defensive backs coach for the Miami Dolphins.
We can then say that Duker has knowledge both of the type of defense Aaron Glenn wants to run and the AFC East.
In Duker’s two years as defensive pass game coordinator in Miami, Dolphins finished 7th in net pass yards allowed per attempt in 2024 and 25th in 2025. You can judge for yourself how much Duker was responsible for those numbers.
The Athletic’s Zack Rosenblatt reports that Duker will not call plays on defense. Aaron Glenn will take over those duties.
Head coach Aaron Glenn is expected to take over defensive play-calling duties, according to league sources.
Glenn notably sought to avoid calling plays a year ago when he hired Steve Wilks. Perhaps a year into his tenure he has reevaluated his approach. Or perhaps Glenn feels the need to take over play calling after making a hire who lacks experience calling the plays.
