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.
