Despite the fact the San Francisco 49ers went toe-to-toe with Patrick Mahomes in Super Bowl LVIII, the team still saw fit to fire defensive coordinator Steve Wilks. With no other team jumping at the bit to snatch him up, it appears like Kyle Shanahan accurately judged Wilks' ability as a defensive play-caller.
That didn't stop Aaron Glenn and the three-win New York Jets from bringing in Wilks as their defensive coordinator in Year 1 of a new regime. Glenn wanted someone with past head coaching experience, and Wilks has a very long career in the NFL as both a coordinator and a fill-in head coach.
