There’s rumours that Mark Davis is getting itchy feet about some of these big names that might be available, like Belichick and Harbaugh, which is steering him away from what would be the logical decision in retaining Antonio Pierce.
I think AP has done enough to deserve a shot, although the offense needs a complete overhaul regardless of who gets the gig. New OC, new QB, new OL.
ETA - there’s always a couple of unexpected firings. I’ll guess the list of HC vacancies are:
Raiders
Panthers
Chargers
Commanders
Patriots
Titans
Saints
