Brock Purdy vs Caleb Williams
Caleb Williams holds a 42.7% edge in Superflex dynasty value.Updated 9/18/2026
THE CASE FOR PURDY
Purdy is a proven high-efficiency QB in an elite, stable ecosystem with strong coaching and playmakers, giving him a bankable weekly floor for contenders. He’s already demonstrated he can deliver top-12 stretches when the offense is healthy, and his value is less dependent on rushing variance. If/when he gets a long-term deal, the “system QB” discount can shrink quickly while you keep harvesting points.
THE CASE FOR WILLIAMS
Caleb has the premium dynasty profile: early-career age, first-round insulation, and the upside to become a multi-year top-5 QB if the rushing/creation translates. Even with early volatility, the market will usually keep him expensive through Year 2, which protects liquidity for rebuilders. If he hits, you’re buying an asset that can anchor a roster for a decade and widen your advantage at the scarcest position.
VERDICT BY TEAM SITUATION
Lean Purdy if you’re trying to win now and can use the 33.9% value gap to add a strong starter/pick on top, unless you specifically need Caleb’s ceiling to beat an elite league.
Lean Caleb—age, insulation, and true difference-making QB1 overall upside fit a rebuild better than paying for Purdy’s lower-ceiling profile.
At a 33.9% gap, this isn’t close in pure dynasty value—Purdy only makes sense straight up if you’re firmly contending and extracting meaningful plus-value alongside him.

Superflex?
In SF, prioritize Caleb’s long-term QB1 ceiling unless Purdy comes with enough extra value to materially improve your starting lineup right now.
