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.

Ben Johnson picked up a few tricks as a mentee to Dan Campbell during his time with the Detroit Lions, and now he's stealing fellow former proteges from his mentor to add to his Chicago Bears coaching staff.
