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?
Career Impact Rank compares entire regular-season careers across NBA history. It combines average league places across the best three, five, and ten seasons, weighted 50%, 30%, and 20%. A lower rank or average place is better.

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.
| Metric | Richard Jefferson | Terry Cummings |
|---|---|---|
| Games | 1,181 | 1,183 |
| Minutes | 34,293 | 33,898 |
3 · Individual skills
Where does each player have an advantage?
These are each player's averages across up to ten best seasons. Career Impact Rank gives the Best 3, Best 5, and Best 10 average league finishes 50%, 30%, and 20% window weights, giving the most weight to the highest peak. The model accounts for position, role, pace, playing time, and team results. Green marks the better result for a metric, including lower turnover rates. Workload and shot-selection measures stay neutral. These rows are not votes toward the ranking.
Shooting
True shooting includes two-pointers, three-pointers, and free throws.

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.
