FDER (FD Efficiency Rating) is our opponent-adjusted efficiency metric — EPA per play, adjusted for schedule across offense, defense and special teams — and it drives the ranked tables. The
FD Line above is a different number: the spread from our market-calibrated power rating model, the same one published on
This Week. Data: 2025 NFL play-by-play, PFR advanced stats, and Next Gen Stats — all via
nflverse. The FD Line is validated out-of-sample; the projected point split and total remain experimental.
