Brock Purdy vs Jacoby Brissett: Who Should You Start?
Deciding between Brock Purdy and Jacoby Brissett is a common lineup dilemma for fantasy managers. The San Francisco 49ers quarterback put up 20.8 PPG in 2025 over 9 games; Jacoby Brissett of the Arizona Cardinals averaged 16.8 in 14. A 4.0-point margin that could shift on any given week.
The per-game difference of 4.0 points favors Brock Purdy, though savvy managers know that gap can shrink or widen depending on the weekly slate. Defensive matchup, recent scoring trends, and health status all shift the calculus from one quarterback to the other.
Both lean on arm talent and offensive scheme as traditional pocket passers. Brock Purdy threw for 2167 yards and 20 touchdowns, while Jacoby Brissett posted 3366 yards and 23 scores. Volume, red zone efficiency, and game script are the key week-to-week differentiators when neither carries rushing upside.
Bye weeks matter for roster construction: Brock Purdy sits Week 9 while Jacoby Brissett is off Week 11. If you are deciding between the two as a season-long roster hold, the staggered byes actually work in your favor.
