Former offensive coordinator Ben Johnson is off to Chicago to lead the Bears. Former defensive Aaron Glenn is now the head coach of the New York Jets. Both will be missed in Detroit, but Campbell and company must move forward with the assistants remaining. That process has already begun.

According to reports, Kelvin Sheppard, who has served as the team's linebackers coach, will be promoted to become the team's next defensive coordinator. The former NFL linebacker has been mentored by Glenn for years and expressed prior to the end of the Lions season he felt ready to run his own defense.
