I can't see Dorsey firing Kitchens mid season even if it is warranted.
I could see it after the season, but I think it's unlikely. He's a first time HC, and it's a bad look for us to fire yet another coach on his first year on the job. Regardless of whether it's warranted or not I just don't think it happens because it will get us nothing but the Mike Pettine's of the world in the future and that's probably worse than sticking with Freddie another year.
He might just need to stop being stubborn about playcalling and give it up next year so he can focus on fixing his coaching flaws like clock management, personnel usage, discipline, etc.
I think he should be fired because his flaws are too many and too significant for me to believe it's just inexperience causing it, but I could be wrong. I think it's more likely he just doesn't have the football IQ or feel for the game for that role, as his deficiencies are things he should already have mastered since he's been around football his whole life playing and coaching and these are some pretty obvious concepts he's failing at.
