San Francisco 49ers made a strategic move by hiring Robert Saleh as their defensive coordinator again, after losing several key defensive players in free agency. Despite these losses, the team retained stars like Nick Bosa and Fred Warner, and began addressing their defensive needs by selecting Mykel Williams and Alfred Collins in the draft. This focused approach allowed the 49ers to replenish their defense effectively, spending their first five picks to target defensive talent. General Manager John Lynch's vision became evident as the team climbed in power rankings post-draft, showing promise for a stronger defense. With health and young talent, the 49ers aim to revitalize their defense and support the offense under head coach Kyle Shanahan, who is looking to regain the team's offensive edge lost in the previous season.
