Box Plus/Minus

Also: BPM

An estimate of a player's per-100-possession contribution vs a league-average player, derived from box score stats.

Definition

BPM uses box score stats plus team context to estimate how many points per 100 possessions better (or worse) a player is than a league-average player. Unlike raw plus-minus, it's team-independent.

Example

A BPM of +8 is MVP-caliber. +5 is All-NBA. +2 is a solid starter. 0 is a rotation-average player. −2 is a weak link.

Why it matters for research

BPM is useful for comparing players across teams and for identifying rising/falling role players whose impact doesn't show in raw stats.
