Brock Purdy vs Caleb Williams

Fantasy Football Comparison for the 2026 NFL Season

The Bottom Line

Brock Purdy is the better fantasy play this season.

This one is genuinely close. Brock Purdy edges Caleb Williams by 1.0 PPG, but both are in the same production tier. The decision comes down to weekly matchup, not season-long resume. If you are choosing between them in a draft, Brock Purdy goes slightly earlier based on volume, but do not reach for the difference.

Low confidence: the production gap is narrow enough that weekly context matters more than the season line.

Fantasy Tiers

Brock Purdy: Tier 2 (Strong Starter) QB (ranked #6 at the position). Caleb Williams: Tier 2 (Strong Starter) QB (ranked #8 at the position). Among the top 32 quarterbacks this season, Brock Purdy is producing at 90% of elite pace and Caleb Williams at 85%. These two are close enough in the rankings that weekly matchup should dictate your start.

Brock Purdy vs Caleb Williams: Who Should You Start?

Brock Purdy (19.7 PPG) and Caleb Williams (18.7 PPG) produced nearly identical fantasy numbers in 2025. When two quarterbacks are this close on a per-game basis, the weekly matchup matters more than the season-long resume. Brock Purdy played 9 games for the San Francisco 49ers; Caleb Williams suited up 17 times for the Chicago Bears.

A 1.0-point per-game gap over a full season is essentially noise. It means one extra catch, one fewer target, or a single broken play away from flipping the script. For a weekly start/sit call between these two, matchup analysis matters far more than the season line.

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 14 while Caleb Williams 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.

Trade Value + Dynasty Outlook

Both are in a similar trade value range. A straight swap would be fair in most leagues, with the tiebreaker going to whichever manager values schedule or bye week more. Dynasty outlook: Brock Purdy (age 26) is in his prime window. Peak production now with steady value for the next 3-4 seasons. Caleb Williams (age 24) is in the early stages of his career with 5+ years of starter-caliber upside. His dynasty value is rising.
