Brock Purdy leads early 2026 passing touchdown totals with 13 through the 49ers' first five games, benefiting from San Francisco's efficient offense and favorable early schedule. Jared Goff sits at 12 with zero interceptions in Detroit's first five outings, while Kirk Cousins and Joe Burrow trail closely at 12 and 11. Key factors include offensive line health, receiver availability, and upcoming divisional matchups that could accelerate or stall volume. Teams with strong rushing attacks or bye weeks may limit passing attempts, whereas high-powered units like the Lions and 49ers position their quarterbacks for sustained production. Historical benchmarks show 30-plus touchdowns typically require consistent 17-game pacing amid variable weather and defensive adjustments later in the season.
