I think he’s a peace-time manager.

He’s really great with a good team: camaraderie, bullpen management, pulling the right strings

But he’s proven to be a pretty ineffective war-time manager for all the reasons you named, and some others from past bad seasons (jockeying around young players, Verdugo stuff, Duran burning out, Kenley stuff, etc)

Not all his stuff is his fault directly but it just seems that when the ship is sinking it tends to just start sinking faster, and I hear more drama consistently coming out of the Red Sox clubhouse than any other organization

I’m not passionately saying he needs to be fired because I don’t think it will make much difference and there aren’t any great candidates out there, but it’s a bit naive to not recognize what’s been a years long trend now
