Brock Purdy vs Michael Penix Jr.: Who Should You Start?
The numbers tell a clear story here. Brock Purdy put up 19.7 fantasy points per game for the San Francisco 49ers in 2025, while Michael Penix Jr. managed 13.4 across 9 games with the Atlanta Falcons. A 6.3-point weekly edge is substantial at the quarterback position.
A 6.3-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 Michael Penix Jr. posted 1982 yards and 9 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 14 while Michael Penix Jr. is off Week 5. If you are deciding between the two as a season-long roster hold, the staggered byes actually work in your favor.
