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 might be soon losing an assistant coach to the New England Patriots. Patriots coach Mike Vrabel is filling out his staff.

It's hard to think of another NFL team that's being punished for their success as much as the Detroit Lions are right now. After losing both of their top assistants to head coaching jobs, the rest of the coaching staff is just continuously getting plundered.

It’s been a long time coming, but Ben Johnson (Chicago Bears) and Aaron Glenn (New York Jets) are off to run their own franchises. Who they take with them is the next question, but what we do know right now is that Dan Campbell is tasked with replacing two of his closest confidants in the middle of a Super Bowl window.
