Coming off a season that saw them lead the league in points allowed, the 49ers defense is undergoing a transition in 2023.
Steve Wilks will replace DeMeco Ryans as defensive coordinator. Ryans used two strong seasons to earn the head coach role for the Houston Texans
In addition to Ryans, the 49ers defense lost 11.5 sacks from last year with the departures of Samson Ebukam, Charles Omenihu, and Jordan Willis.
To make up for the losses, San Francisco made a splash signing with the addition of Javon Hargrave. Hargrave gives the 49ers defensive line a strong pass rushing threat up the middle.
