With the defense. It was a chance in philosophy with McVay. He wanted a DC that adapted to the offense of the week instead of Phillips' we will do X every week regardless of the offense and we will do it well approach. That explains Staley.
As far as the OC or QB coach types, yeah, McVay is running the show, there is no upward movement with McVay calling the plays. So yeah its time to move on. Or move on and up.
As far as replacing Staley, Morris is considered one of the top defensive minds in the NFL. Thats hard for Pleasant to compete with. And maybe McVay thinks he is more of a position coach and not coordinator material.
But yeah, the Rams do seem to go outside a bit for their hires.
