49ers fired defensive coordinator Steve Wilks.
Shanahan scheduled a surprise press conference to announce the news earlier today. The move comes as a bit of a surprise given how well San Francisco’s defense played in Wilks’ first and only season as the defensive coordinator. The 49ers finished the regular season ranked third in points allowed and 10th in EPA per play allowed. Shanahan also said he did not expect any moves within the coaching ranks as recently as Monday, though he noted that he hadn’t talked to any of his staff members about the matter yet. Though the 49ers’ defense arguably came up short in the Super Bowl, they held Patrick Mahomes to 19 points in regulation. Shanahan notably called a timeout late in overtime, seemingly to switch a defensive play called by Wilks. Even if Shanahan didn’t like Wilks’ calls on defense, the move feels more akin to making Wilks the scapegoat for the loss than anything else. San Francisco will now have to hire a third defensive coordinator in as many years. Wilks, who got multiple head coaching interviews during the playoffs, should be able to quickly land another job in the NFL.
