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)
Rivera and Bowles would be my choice of fired HC turned DC. Bowles has proven to be a great DC and the last time Rivera was our DC we went to a super bowl so theres that lol. I want no one from the Cover 2 coaching tree.
