49ers Stock Report: Evaluating the offensive line through five weeks

The San Francisco 49ers’ offensive line has defied expectations in the first five weeks of the 2026 season, emerging as one of the NFL’s most consistent units despite skepticism from analysts and fans. Head coach Kyle Shanahan has publicly dismissed criticism of the line, and the results—including a top-five ranking—speak for themselves.

The group’s cohesion is evident even with rookie Connor Colby at left guard, while Jake Brendel has set a league-leading streak of 921 consecutive snaps without allowing a sack, a mark that underscores the unit’s reliability. Pressure distribution across the line reveals standout performances from Trent Williams (11.6%) and Colton McKivitz (18.6%), with Brock Purdy’s first sack of the season coming against Seattle’s elite defensive line, highlighting both the line’s resilience and the quarterback’s improved pocket presence.

The 49ers’ investment in the unit—through trades, draft picks, and free agency—has paid off without relying on first-round talent, as players like Dominick Puni and Colby continue to develop under offensive line coach Chris Foerster.
