The Rams had never announced Ryan's hiring. When news broke that Ryan would be hired, a Rams official could not confirm the story. The official said Ryan was scheduled to visit team headquarters the next day, but that nothing was imminent in terms of a hiring.
ESPN's Chris Mortensen says the Rams changed their mind on Ryan. The Rams said they decided against hiring Ryan after "extensive" discussions about defensive philosophy.
This is a good non-hire by the Rams if Ryan were indeed unable to adjust. The Rams did not need a schematic overhaul on defense. They needed someone to coach the defense.
