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?

2 · Playing time and responsibility
How much did each player take on?
Read games and minutes alongside impact. Offensive usage is the share of team plays a player ends with a shot, free throws, or a turnover while on court. More usage is not automatically better.

What happened with and without them?
A verified with/without comparison is unavailable for this scope. We do not substitute another season’s observations.
Four separate questions
Impact, winning, playoffs, and awards
These are different ways to understand a career. Only Regular Season Impact determines the hussEyquation verdict. The other three sections add basketball context without adding points or changing the rank.

How each context field is counted
- Listed-team regular-season wins
- The sum of each listed team's final wins in every season the player represented that team.
- Listed-team winning percentage
- Those team wins divided by those teams' total regular-season games.
- 50- and 60-win team seasons
- Listed team-seasons that finished with at least 50 or 60 wins. Shortened seasons are not projected to 82 games.
- Team seasons reaching playoffs
- Listed team-seasons in which that team qualified for the playoffs.
- Playoff appearances and games
- Postseasons and games in which the player appeared.
- Team playoff wins
- Team wins from those postseasons. They describe team results, not individual credit.
- Finals appearances and championships
- Seasons when the player appeared in the playoffs for the finalist or champion.
- Awards
- Recorded NBA selections and major regular-season honors. A zero means the source records none; Not available means the source field is missing.
