Brock Purdy vs Justin Herbert
Justin Herbert holds a 8.6% edge in Superflex dynasty value.Updated 9/19/2026
THE CASE FOR PURDY
Purdy is 1.8 years younger and tied to an elite, efficient Shanahan ecosystem that consistently manufactures QB-friendly production. His weekly floor is buoyed by pace/efficiency and surrounding talent, and he’s already shown he can deliver top-end spike weeks when the TDs swing his way. At a ~22% discount to Herbert, he’s a strong value pivot if you want to reallocate the savings into a second starter/RB/WR without punting QB1 output.
THE CASE FOR HERBERT
Herbert has the cleaner long-term bet for sustained top-6 QB seasons because the arm talent, volume ceiling, and organizational investment are bankable. His profile is less scheme-dependent and more resilient to supporting-cast volatility, which matters in dynasty where situations change fast. If you’re buying a cornerstone QB to anchor Superflex for the next 4–6 years, Herbert is the safer elite asset even at the premium.
VERDICT BY TEAM SITUATION
Herbert if you can pay the premium without stripping depth; otherwise take Purdy plus the difference to strengthen the starting lineup.
Herbert, because his insulation and market liquidity are better for a multi-year build and future re-roll flexibility.
Close, but the gap is slightly rich—Purdy is the better value at cost while Herbert is the better pure asset.

FREQUENTLY ASKED
Worth more?
Justin Herbert is worth more, but a 21.9% gap is near the upper end of what I’d pay over Purdy in most formats.
Trade?
If moving from Herbert to Purdy, ask for a strong added piece (mid 1st or equivalent starter value); if moving from Purdy to Herbert, try to cap the add to a late 1st/2nd-tier starter.
Superflex?
In Superflex, prioritize Herbert for elite-QB insulation, but Purdy is a viable QB1/2 value if the savings materially upgrades your second QB or flex spots.
