Assuming we hire a young offensive coach, we will need an experienced defensive play caller - which will consist of fired HCs and DCs (likely won’t have an up and coming DC. A lot of fired HCs end up as defensive coordinators: Dan Quinn, Brian Flores, Vic Fangio, Rasheed Morris (interim), Steve Wilks (interim), Jack Del Rio (lol).
Candidates: Belichick (no shot), Brandon Staley (runs a 3-4), Ron Rivera (intriguing), Todd Bowles (not sure he gets fired), Jack Del Rio (lol)
If you think Eberflus is bad. Do not bring in Staley.
