Thank you for this.
Fisher did add credibility to the team when he arrived. We went from a laughing stock to being mentioned as a playoff darkhorse. The players liked playing for him, he attracted a number of free agents and assembled a quality defense.
Unfortunately all that was undermined by his dismal offenses, partly because of philosophy and partly because no coordinator of quality would come near him. Think of how things might have been different if he hadn't passed on Hue Jackson for Brian Schottenheimer.
I'd never hire him as a head coach, but I'd hire him as a DC in an instant
