3. Tanner Engstrand, Passing Game Coordinator
Engstrand is on the same track as Johnson, first working as the Lions' tight ends coach, then moving to tight ends coach and passing game coordinator when Johnson became the offensive coordinator. This season, Engstrand's lone title is passing game coordinator. Also like Johnson, Engstrand is a former college quarterback.
At 41 years old Engstrand has a wide swath of coaching experience going back to 2005. Check out his resume, from the college level (Jim Harbaugh disciple?) to the XFL to the NFL.

If Johnson takes a head coaching job, Engstrand would be the obvious internal candidate to replace him. But if Johnson were to decide to stay in Detroit again, or even if he does leave, other teams/new head coaches have surely noticed Engstrand enough to possibly consider him for an offensive coordinator job. If Johnson or Glenn takes a head coaching job, they may want to bring him along as their offensive coordinator.
