All-Time Chiefs QB Rankings
FAQ
Who is the greatest Kansas City Chiefs quarterback of all time?
Patrick Mahomes holds the top spot with a rating of 78.81, driven by his “Great” regular-season performance, “Great” fantasy impact, and “Elite” playoff showings across 9 seasons, earning them “Aura” status as the franchise’s iconic figure.
How does Patrick Mahomes compare to the greatest quarterback of all time?
Tom Brady is the greatest quarterback in the history of the NFL. His highest rating is with the New England Patriots—a fitting 133.7—and overall is even higher because of his Super Bowl win with Tampa Bay. Patrick Mahomes’s 78.81 with the Chiefs, while leading the team to three Super Bowl victories, earning two NFL MVP awards, and three Super Bowl MVPs over nine seasons,
doesn’t match Brady’s sustained excellence across eras—his overall rating with both Tampa and New England totals 148.5.

What is the difference between HeyTC’s QB Rating and ESPN’s QBR?
QBR is an outdated model that doesn’t take into account whether the quarterback won the game—its first flaw. Winning is everything; who cares if Quarterback X has the highest QBR but doesn’t win games? Its second flaw is that it doesn’t factor in playoff and Super Bowl success.
By contrast, the HeyTC QB Rating is a composite score evaluating a quarterback’s tenure with his team, factoring in regular-season performance, fantasy football value, playoff success, and overall franchise legacy.

What do the “Season,” “Fantasy,” and “Playoffs” columns mean?
These columns use qualitative tiers to assess regular-season excellence (e.g., Good for standout play), fantasy (e.g., “Elite” for top scorers), and postseason performance (e.g., “Great” for significant playoff runs)—forming the foundation of the overall ranking.
How do Kansas City Chiefs quarterbacks compare to other teams?

What do the slang terms in the “Overall” column mean (like “Aura,” “Sigma,” or “NPC”)?
These terms, inspired by our “Dad Glossary,” add a playful, informal spin to describe quarterback impact:
- Aura/Elite: Legendary, game-changing dominance.
- Sigma/Great: Consistently elite performers.
- Slaps/Good: Solid, reliable contributors.
- Chill/Average: Dependable but unremarkable.
- Delulu/Mediocre: Overhyped with underwhelming results.
- NPC/Subpar: Forgettable and inconsistent.
- Cooked/Non-Factor: Complete busts.
How often is this list updated?
