Dan Pompei of the Chicago Tribune wrote an article on Fisher's behalf a few months ago. It's a hard read because it's written entirely in the 2nd person. Fisher may as well have wrote the thing himself.

Regarding the coordinators, this is how Fisher sees it:
"You were never an offensive coach. You hired others to do that. And that's where things unraveled. After the 2014 season, your offensive coordinator, Brian Schottenheimer, wanted to be closer to his family, so he told you he was leaving for a job at the University of Georgia.
Your intent was to replace him with an experienced NFL play-caller. You reached out to four coaches who had been successful NFL coordinators. Three of them also had head coaching experience. None of them wanted to be your coordinator. "My sense," you say, "is they didn't want to have to endure the relocation."
So you promoted from within. It didn't work once. You made a change and tried another promotion. Your team didn't have Robert Woods, Sammy Watkins and Cooper Kupp for your quarterbacks to throw to, so it wasn't ideal for your coordinators.
"Had I stayed," you say, "there were a lot of changes I needed to make that we had been unable to make because of the move."
