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.

DETROIT – The Detroit Lions have promoted an assistant coach to become their new defensive coordinator. Linebackers coach Kelvin Sheppard is expected to replace Aaron Glenn as the Lions' new DC, according to multiple reports. Sheppard joined the Lions in 2021 and has quickly risen through the defensive coaching ranks for head coach Dan Campbell.
