The New York Jets' defense has experienced a significant decline this season, culminating in their worst performance in years during a 48-20 loss to the Jacksonville Jaguars. Following this game, Jets head coach Aaron Glenn fired defensive coordinator Steve Wilks, who was in his first season with the team. The decision was made late Sunday night and announced on Monday morning, with Chris Harris, the Jets' defensive backs coach and passing game coordinator, stepping in as interim defensive coordinator. The Jets' defense struggled notably, allowing scores on eight of the first nine Jaguar drives and failing to generate sacks or turnovers, with only two quarterback hits. Trevor Lawrence delivered a historic performance, throwing five touchdown passes and rushing for another, as the Jets' defense allowed a total of 48 points—the most since 2021. The team has also gone 14 consecutive games without an interception, tying an NFL record for futility. The defense has allowed 82 points over the past two games and ranks poorly across multiple defensive metrics, including points allowed, red zone defense, and sack rate. Wilks, who previously served as a defensive coordinator for the 49ers and Browns, was dismissed after a series of underwhelming performances, with the Jets now 20th in total defense and 30th in points allowed. The team faces an uncertain future with personnel changes expected in the offseason, as they aim to rebuild a struggling unit with significant draft capital and cap space. Glenn emphasized the importance of character and team effort over X’s and O’s, and the change reflects a desire to improve defensively before the season concludes.
