On/off net rating: huge at the top, near zero in the middle

In the 2025-26 slice, Victor Wembanyama posts the biggest on/off net-rating swing at +17.043 per 48 -- yet the median qualified player sits at just +0.127, so most on/off gaps are noise around zero.

What it means

On/off net rating asks how much better a team's point differential is with a player on the floor versus off it. The stars separate hard -- Wembanyama in 2025-26, Jokic at +23.713 the season before -- but the full distribution hugs zero, which is the point: a big on/off number is rare and easy to misread. Who a player shares the floor with is tangled up with coach trust, opponent strength, and garbage-time minutes, so the raw delta flatters bench-anchoring bigs and punishes stars whose backups happen to play easy minutes.

Caveats & confounds

ROSTER CONFOUND: this on/off delta is NOT a causal player-impact estimate -- floor-sharing correlates with coach trust, opponent strength, and garbage-time usage, none controlled for. DESCRIPTIVE_ONLY until an earned predictive-validity receipt says otherwise.
