The Jets introduced former Detroit Lions coordinator Aaron Glenn as their next head coach Monday. The Lions hired Kelvin Sheppard as their next DC.

The Lions continue to lose high-level staffers after their offensive and defensive coordinators left the team for head coaching jobs.

Detroit might be on the hunt to replace its offensive and defensive coordinators, with Ben Johnson and Aaron Glenn receiving head coaching buzz.

Aaron Glenn coached the Detroit Lions defense from 2021-24 before being hired as the next New York Jets head coach. Is he the next Dan Campbell?

The Detroit Lions have acted quickly and promoted from within to fill the role of defensive coordinator. The Lions are promoting linebackers coach Kelvin

The New York Jets introduced new head coach Aaron Glenn, the former Detroit Lions defensive coordinator, on Monday as owner Woody Johnson and his staff attempted to turn the page on a harshly disappointing 2024 season.

Coach Dan Campbell has been looking to fill both of his coordinator openings following the departures of Ben Johnson and Aaron Glenn to the Chicago Bears and New York Jets, respectively, as their new head coaches. Detroit is set to promote linebackers coach Kelvin Sheppard to defensive coordinator, a team source told The Athletic last week.

The Detroit Lions couldn’t take care of business this season. Despite being arguably the best regular-season team in the NFL, they couldn’t win a single playoff game. That was a big blow for Dan Campbell.

There are still some holes on the staff to fill. But the two biggest questions have been answered, with the Detroit Lions landing on John Morton as offensive coordinator and Kelvin Sheppard as defensive coordinator.
