Leaderboards and Box vs LineupEach family in both forms, side by side: the rating, then its percentile among the season's players with that form (the bar). Lineup RAPM: on-court possessions from play-by-play, one regularized regression over the season. Box Elo: game totals spread by minutes; cannot separate teammates; for seasons without play-by-play. Each is an on-floor team-rate impact, not the player's own count. Lineup RAPM is not published for 2026-2027 (apart from RAPM itself).
