Brock Purdy vs Sam Darnold: Who Should You Start?
The numbers tell a clear story here. Brock Purdy put up 20.8 fantasy points per game for the San Francisco 49ers in 2025, while Sam Darnold managed 14.7 across 17 games with the Seattle Seahawks. A 6.1-point weekly edge is substantial at the quarterback position.
A 6.1-PPG gap gives Brock Purdy the edge on paper, but paper does not account for Thursday night matchups, weather games, or a star defender returning from injury. The real question is not who was better in 2025, but who is the better start this specific week.
Both lean on arm talent and offensive scheme as traditional pocket passers. Brock Purdy threw for 2167 yards and 20 touchdowns, while Sam Darnold posted 4048 yards and 25 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 Sam Darnold is off Week 10. If you are deciding between the two as a season-long roster hold, the staggered byes actually work in your favor.
