Surprisingly Snow didn't leave with Rhule. He might have left on his own, but we'll never know. Wilks fired Snow. Wilks had disagreements before, saying Snow wasn't running an NFL defense. So far, Wilks' NFL D is worse than Snow's.
He also fired a ST coach, cause you know, the problem early in the season was with the D and ST, obviously. /sarc
After the Bengals humiliation Wilks fired cornerbacks coach Evan Cooper and defensive line coach Paul Pasqualoni, clearly scapegoating since the D looks worse since Wilks took over and his D in Arizona was absolute dogshlt.
He left the nonperforming O staff in tact.
