I doubt a regime change will happen unless Josh demands it. Or at the very least, is consulted and agrees to it.
Just a hunch, but I feel Josh might still be loyal to Sean. Josh doesn't look like the kind of player to make demands like that. But a couple more years of not achieving the goals, and Josh creeping up on his mid-30s, might change that. But I would certainly welcome a regime change next year.
The blueprint is flawed. The scouting is off. The contracts are mistakes. We are wasting a first-ballot HOF QB.
