Knox Intelligence · Historical
KV-H (Knox Value Historical) — a career-quality score for every NFL player in the encyclopedia, computed from era-relative z-scores. A player is measured against their own era’s peers, not all-time averages, so seasons from the 1980s and the 2020s are directly comparable.
Algorithm
Coverage note: gamesPlayed data is richest for the nflverse era (1999+). Pre-1999 seasons without gamesPlayed are excluded (honest gap, not zero). Legends with pre-1999 peak careers (Rice, Elway, Sanders) will appear lower than their true historical rank. 7,317 players scored.
