Brock Purdy vs Caleb Williams: Who Should You Start?
Two quarterbacks who will land on plenty of the same rosters in 2026. Brock Purdy (San Francisco 49ers) finished the 2025 season averaging 20.8 fantasy points per game in 9 games. Caleb Williams (Chicago Bears) came in at 19.1 PPG over 17 games. The gap is real but not insurmountable with the right matchup.
Brock Purdy carries a 1.7-point PPG advantage from the 2025 season. That baseline matters, but it is one input among several. Matchup difficulty, scoring trends, and injury reports move the needle week to week, which is why the best answer changes depending on when you are asking.
Both lean on arm talent and offensive scheme as traditional pocket passers. Brock Purdy threw for 2167 yards and 20 touchdowns, while Caleb Williams posted 3942 yards and 27 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 Caleb Williams is off Week 7. If you are deciding between the two as a season-long roster hold, the staggered byes actually work in your favor.
