Jets hire former Dolphins assistant Brian Duker as defensive coordinatorBy Canadian Press on January 28, 2026. The New York Jets hired former Miami Dolphins assistant coach Brian Duker as their defensive coordinator on Wednesday. Glenn was Detroit’s defensive coordinator for four seasons before being hired as head coach by New York last year and has familiarity with Duker. Duker replaces Steve Wilks, who was fired late in the season after the Jets defense had a miserable showing in a 3-14 season. Chris Harris, the defensive backs coach and pass game coordinator, served as the interim defensive coordinator for the final three games.
