For the San Francisco 49ers, the defensive front was once a strength of the team, consistently disrupting opposing quarterbacks and overwhelming offensive lines. That wasn't the case last season, however, as the unit recorded just 20 sacks—the fewest in the NFL. Determined to rebuild the defensive line, the 49ers used their top pick in the 2025 NFL Draft to select Mykel Williams, hoping the talented rookie could provide an immediate impact while developing into a cornerstone of the defense.
