Caleb Williams vs Patrick Mahomes

Fantasy Football Comparison for the 2026 NFL Season

The Bottom Line

Patrick Mahomes is the better fantasy play this season.

Patrick Mahomes is the better play on a neutral week. 20.4 PPG with 3,999 yards gives a reliable baseline. Caleb Williams at 18.7 PPG is not far behind and could win specific weeks where matchup and game script align. Draft Patrick Mahomes higher, but do not fade Caleb Williams entirely.

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

Fantasy Tiers

Caleb Williams: Tier 2 (Strong Starter) QB (ranked #8 at the position). Patrick Mahomes: Tier 1 (Elite) QB (ranked #4 at the position). Among the top 32 quarterbacks this season, Caleb Williams is producing at 85% of elite pace and Patrick Mahomes at 93%. That ranking gap means Patrick Mahomes carries more trade value and a higher draft cost in 2026.

Caleb Williams vs Patrick Mahomes: Who Should You Start?

Deciding between Caleb Williams and Patrick Mahomes is a common lineup dilemma for fantasy managers. The Chicago Bears quarterback put up 18.7 PPG in 2025 over 17 games; Patrick Mahomes of the Kansas City Chiefs averaged 20.4 in 14. A 1.7-point margin that could shift on any given week.

The per-game difference of 1.7 points favors Patrick Mahomes, 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.

Patrick Mahomes offers meaningful rushing upside with 422 yards on the ground in 2025, which separates his floor from a pocket passer like Caleb Williams (3942 passing yards, 27 touchdowns). In games where the passing matchup looks ugly, that rushing production can be the entire difference on a start/sit call.

Caleb Williams has his bye in Week 5, and Patrick Mahomes rests in Week 10. Managers rostering both need waiver wire depth at quarterback for those two weeks, and that is exactly the kind of planning DraftCall's matchup engine surfaces automatically so you are not scrambling on a Sunday morning.

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: Caleb Williams (age 24) is in the early stages of his career with 5+ years of starter-caliber upside. His dynasty value is rising. Patrick Mahomes (age 30) is in his prime window. Peak production now with steady value for the next 3-4 seasons.
