Brock Purdy vs Sam Darnold
Brock Purdy holds a 48.9% edge in Superflex dynasty value.Updated 10/2/2026
THE CASE FOR PURDY
Purdy is a locked-in starter attached to an elite 49ers offensive environment with high weekly efficiency and TD equity. At 26.6, he offers a longer runway than Darnold while already producing as a reliable QB1/QB2 in Superflex. The 36.7% value gap is justified by role security and a clearer multi-year outlook.
THE CASE FOR DARNOLD
Darnold is a cheaper path to usable Superflex starts if he’s holding a starting job, making him a pragmatic contender buy when you’re allocating assets elsewhere. Seattle’s weapons can support spike weeks if the volume and TDs cooperate, so the short-term points per cost can be attractive. If he strings together competent play, there’s a non-zero chance his market value rebounds quickly from a low base.
VERDICT BY TEAM SITUATION
Take Purdy unless you specifically need to turn him into multiple win-now pieces and can replace his weekly floor with Darnold plus surplus value.
Purdy is the clear hold/build piece; Darnold is a flip candidate the moment he gains any perceived job security.
This isn’t close in dynasty—Purdy’s age-plus-stability profile makes him worth paying the gap in most formats.

Superflex?
In Superflex, prioritize Purdy as a stable QB1/2 anchor, while Darnold is a contingent QB2/3 you roster for short-term starts and liquidity plays.
