What happened: Josh Allen leads 37 qualifying quarterbacks at plus-35.4 total EPA on dropbacks, followed by Brock Purdy at plus-31.7. Aaron Rodgers ranks 37th at minus-42.4 with a minimum five dropbacks via NextGenStats.
Why it matters: Dropback EPA isolates quarterback passing efficiency from rushing and special-teams noise. A gap of nearly 78 points between first and last marks an extreme early split in passing production.
By the numbers: Allen +35.4, Purdy +31.7; Rodgers -42.4 finishes 5.9 points below 36th place.
What to watch: Watch whether the leaderboard compresses as dropback samples grow in coming weeks.
