What is the Devils Performance Index?
Hello. My name's Stephen. I'm a Devils season ticket holder and a fan from Stevens to Hischier.
The Devils Performance Index is a means of quantifying gameplay beyond the box score. It uses
play-by-play data to track individual shot attempts (Corsi), expected goals from shot location,
and penalties drawn — all filtered for 5-on-5 play.
The formula
rewards offensive production most heavily (goals and assists), but also credits shot quality,
physical play (hits, blocks, takeaways per 60 minutes), and discipline. It penalizes turnovers
and penalties. Defensemen get bonuses for scoring and shot generation, and goalies
are judged on saves, goals allowed, and wins.

About the DPI
The Devils Performance Index is a custom metric designed to evaluate player performance on a game-by-game basis. It uses play-by-play data to capture individual shot attempts (Corsi), expected goals from shot location, and penalties drawn. Physical stats are normalized to per-60-minute rates so that ice time doesn't inflate raw counts. A 5-on-5 bonus rewards even-strength play quality.
