An off night is a game where a player's points per minute (PPM) fall below par. See how often basketball greats from around the world had one, measured against a fixed bar or against their own career average.
Any game under this many points per minute (PPM) counts as an off night — same standard for everyone, regardless of role or era.
A game is an off night if the player scored under X% of their own career PPM — holding superstars to a higher standard.
These players starred in leagues or eras without public game-by-game records, so they can't be ranked on off nights. Their career numbers are shown here instead, as published — not measured the same way as the rankings above.
