You can't cut Carr next year, so who can fix him?

I've watched them but I think he's done well with Cassel, he took on a bad situation in Washington but I don't put that on him. The team is nosediving.
It's Sam Howell. And he's a decent QB. But the play calls come from EB. I've watched most of their games since I live in suburban DC. EB is just not a good (more like terrible) situational play caller this season.
