What these measures mean
- Box impact
- Estimated points per 100 possessions above that season's league average, from the historical box-score model. Zero is league average; higher is better. Historical defense estimates are included where labeled. This is not the live model's lineup-adjusted estimate.
- Impact Rate
- A 0–100 score comparing performance within one season. Higher is better. This is a score, not points per possession.
- Impact estimate
- The season model's final estimated points per 100 possessions above league average, before conversion to the 0–100 Impact Rate score. It includes lineup evidence where available. Zero is league average; higher is better.
- Impact Rate rank
- The player's place among qualified players in that season's Impact Rate ranking. No. 1 is best. This is a rank, not an impact score.
- Value contribution / Season Value
- Completed seasons use a fixed-baseline contribution to Career Value. The live season instead uses Season Value, combining that season's impact with workload.
- Career Impact Rank
- An all-time rank weighted toward the player's best three, five, and ten seasons.
