Four games. Zero sacks. Are you kidding, 49ers?

October 8, 2026

The San Francisco 49ers have defied NFL norms with an unprecedented start to the season, going four games without allowing a single sack. In an era where defensive units constantly target quarterbacks, the 49ers’ offensive line—led by left tackle Trent Williams and quarterback Brock Purdy—has created an impenetrable barrier.

This marks the first time since the 2005 Peyton Manning-led Colts that a team has begun a season with four consecutive games without surrendering a sack, a feat achieved by only four other franchises since 1963. The last occurrence was over two decades ago, underscoring just how rare this achievement is.

Coach Kyle Shanahan expressed surprise at the collective effort, noting that the offensive line’s cohesion and preparation have been pivotal. General manager John Lynch emphasized the value of experience, highlighting how the unit’s chemistry has elevated their performance.

Purdy has thrived with the protection, crediting the line’s daily dedication in meetings and practice for translating into dominance on Sundays. Williams, a cornerstone of the unit, has long believed in their potential to rank among the NFL’s best, and their early-season success is already delivering on that promise.
