The reason why I say consider firing Belichick is because any other coach in the league did what he did and put Patricia in charge of both the play calling duties and the offensive line and Judge as QBs coach and they failed as miserably as they did, that head coach would be fired.
Belichick made these moves against Kraft's objections. Kraft said that Belichick has earned the right to make these head scratching moves because he is the GOAT. But that also tells me that, he might have used up most of his GOAT clout with Kraft already.
If Belichick is back next year which I expect he will, he will most likely have to produce or he may not break Shula's record with the Patriots. I think he will need that playoff win next year or he is done with the Patriots. But some of Kraft's words this past offseason about how this team needed to get a playoff win and his not being on board with Patricia means that I wouldn't be shocked if Belichick "resigns", is fired, or traded before the playoffs is over.
