He previously served as the pass game coordinator for the [Miami Dolphins](/source/Miami_Dolphins). Duker attended [Towson University](/source/Towson_University). He previously served as an assistant coach with the [Detroit Lions](/source/Detroit_Lions), [Baltimore Ravens](/source/Baltimore_Ravens), [San Francisco 49ers](/source/San_Francisco_49ers), [Cleveland Browns](/source/Cleveland_Browns), [Missouri](/source/Missouri_Tigers_football), and [Bryant University](/source/Bryant_Bulldogs_football).[1] ## Coaching career ### Bryant University Duker began his coaching career at [Bryant University](/source/Bryant_Bulldogs_football) as a Graduate Assistant for two seasons. ### University of Missouri Duker then moved on to the University of Missouri where he served as a graduate assistant and then defensive quality control on [Gary Pinkel](/source/Gary_Pinkel)'s staff. The Tigers reached the SEC Championship game both of the seasons Duker was in Columbia. ### Cleveland Browns Duker joined the [Cleveland Browns](/source/Cleveland_Browns) as a defensive intern in 2015 under [Head Coach](/source/Head_Coach) [Mike Pettine](/source/Mike_Pettine). ### San Francisco 49ers Duker joined the [San Francisco 49ers](/source/San_Francisco_49ers) as a defensive analyst in 2016 under [Head Coach](/source/Head_Coach) [Chip Kelly](/source/Chip_Kelly). ### Baltimore Ravens Duker joined [John Harbaugh](/source/John_Harbaugh)'s staff with the [Baltimore Ravens](/source/Baltimore_Ravens) as a defensive staff assistant in 2018 and then spent 2019-2020 as a defensive coaching analyst. ### Detroit Lions Duker left Baltimore to join [Dan Campbell](/source/Dan_Campbell)'s [Detroit Lions](/source/Detroit_Lions) staff[2] in 2021. He initially served as a Defensive Assistant. After the 2021 season, he was promoted to Safeties Coach. During the 2022 season he was promoted to interim defensive backs coach[3] when [Aubrey Pleasant](/source/Aubrey_Pleasant) was let go following the Lions Week 8 loss to the Miami Dolphins. Following the growth of the Lions defensive secondary, the team confirmed that Duker would continue as the defensive backs coach in 2023.[4] The Lions young secondary players showed great growth under Duker's direction. Kerby Joseph blossomed into a feared player.[5] As a rookie, [Brian Branch](/source/Brian_Branch) was also quick to experience success in the NFL.[6] ### Miami Dolphins Duker left the Lions to become the [Miami Dolphins](/source/Miami_Dolphins) Secondary Coach and Defensive Passing Game Coordinator[7] in early 2024. Before the 2025 Season, NFL analysts believed the Dolphins would struggle because of lack of secondary talent.[8] During the second half of the 2025 season, pundits felt that the Dolphins secondary was vastly outplaying that preseason assessment.[9] ### New York Jets On January 28, 2026, the [New York Jets](/source/New_York_Jets) hired Duker as their defensive coordinator under head coach [Aaron Glenn](/source/Aaron_Glenn).[10] ## Personal life Duker was born on July 15, 1989, in [Maryland](/source/Maryland).[11] He earned a bachelor's degree from [Towson University](/source/Towson_University), where he was a student assistant, and his MBA from [Bryant University](/source/Bryant_University).
