Brock Purdy has opened the 2026 NFL season with 11 passing touchdowns through four games for the undefeated San Francisco 49ers, leading the league while posting a 69.9% completion rate, 126.2 passer rating, and zero sacks allowed. The Kyle Shanahan offense continues to generate explosive plays despite mounting injuries to key contributors like Mike Evans and Trent Williams, with Purdy connecting frequently on deep strikes and red-zone opportunities. His mobility has added a dimension on designed runs and scrambles. Upcoming tests include a Week 5 road matchup against the Seahawks' stout defense, followed by a demanding schedule that could test volume and efficiency over 17 games. Trader sentiment reflects this early dominance and the 49ers' offensive continuity, tempered by typical regression risks and roster attrition.
