Quarterback EPA per Dropback Leaders
Quarterback EPA per Dropback — 2023 NFL leaders, updated Aug 13, 2026. Brock Purdy (SF) led the league in expected points added per dropback at 0.31, ahead of 38 other qualifying players. Based on verified 2023 play-by-play data (nflverse); Half-PPR scoring. Through the 2023 season.
Expected points added per dropback asks what each pass attempt was worth; success rate asks how often the attempt simply worked, with no credit for the size of the gain. Read them together. A quarterback high in the first and low in the second lives on explosive plays and disappears for stretches; high in both is the profile of an offense that stays on schedule. The dropback is the honest denominator because it charges a passer for the snaps that never became throws — a sack and a scramble are both quarterback outcomes, and a passer whose per-attempt line looks tidy because he takes the sack instead of testing the coverage is exactly who this separates.
