NFL Dynasty Tracker

Every sustained era of NFL dominance — consecutive seasons at 60%+ win rate with a minimum of 3 seasons. Dynasty Score = avg win% × length × 10 + championships × 15. Gold bars = championship seasons.

Dynasty Score rewards sustained excellence over flash-in-the-pan single seasons. A 10-year dynasty with 3 titles outscores a 5-year dynasty even with the same average win%.· 90 dynasties across NFL history
