Every NBA possession, reconstructed.

Five-man lineups, on/off swings, and IPM, our own impact metric, all computed from play-by-play we rebuild ourselves. Nine seasons, shaded by league percentile.

Net rating per 100 possessions, Regular Season.

All 30 teams, nine full seasons of lineup data.

We built our own EPM-family metric.

IPM is the RAPM we compute from reconstructed play-by-play, re-fit to shrink every player toward a box-score prior trained on nine seasons of our own data. Stable and current at once.

Tested before it shipped

For every season since 2017-18 we froze the metric on part of the data and made it predict games it had never seen, against pure RAPM, the box prior alone, and a league-average baseline.
