This thread is a little premature as there's still a whole lot left of this season. We still have 5 regular season games, nearly 30% of our schedule, left to play, plus the playoffs.
I don't like seeing us move on from any coach after just one season, especially when the entire staff was new. But on the flip side, Pete stuck with his OC's too long, especially Bevell, who should have been fired a week after SB 49. Loyalty is an admirable trait in a lot of situations, but not that one.
As far as what actually happens, IMO it depends on how much Macdonald was on board with the hire. If he was against it, I could see him lobbying for a change. My guess is that he stays.
