  • Player Index (PLI) — A measure of how valuable a player is to a franchise given the player's contract value, production, availability, and overall impact both in the regular season and postseason. Scored 0–100, graded D- to S+.
  • Potential Index (POI) — A measure of how high a player's PLI can be: the player's projected PLI ceiling if they continue their current trajectory next season. Same 0–100 scale and grade thresholds as PLI; shown only for players under 25. POI blends the legacy formula (45%) with the Performance Potential Score / PPS from per-100 stats (55%).
