Box Plus/Minus (BPM)
An estimate of the points per 100 possessions a player contributes above league average, derived from box score stats. Broken into offensive (OBPM) and defensive (DBPM) components.
Like a restaurant's profit contribution per customer — it measures value added above the baseline, accounting for both revenue and cost.
Why it matters
BPM quantifies a player's total impact per possession, making it useful for estimating how much a team's offense or defense changes when a player sits.
How DMP uses this
DMP references BPM-style impact estimates when calculating redistribution effects — higher-impact players create larger redistributions when they're absent.
Common mistake
Using BPM to evaluate individual game performance — it's designed for season-level evaluation and is noisy on a game-by-game basis.
