Read turnover rate alongside offensive workload. Offensive usage measures the share of team plays a player ends with a shot, free throws, or a turnover while on the court—not every touch, pass, or act of playmaking. These rows provide context; they are not extra points added to the ranking.
Regular season only. Impact figures are estimates; small gaps are not exact. Playoffs, awards and titles do not determine the verdict.
Behind the estimate
Why the model rates them this way
A verified breakdown of this season’s published estimate is unavailable. We do not substitute another season’s calculation.
What this does not establish: these figures do not prove that either player made his teammates shoot better. A verified teammate-shooting comparison is unavailable for this selected season. A small difference in the estimates is not a decisive basketball distinction.

Understand the numbers
Start with impact, then compare playing time and skills. Team results add context. These are not categories to tally into a winner.
1 · Ranking evidence
Impact: who ranks higher, and why?
The impact estimate compares performance while playing, not total contribution over the season. The individual-stat estimate plus the lineup adjustment gives the final estimate.
