Impact comparison

Box impact estimates points per 100 possessions above each season's league average. Higher is better. Career ranks and average league finishes work the other way: lower is better.

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.

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. Statistics that were not recorded in earlier eras are left out. 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.

Passing

Assist rate is the share of teammates’ made shots assisted while the player is on court. Read turnovers alongside offensive workload; lower turnover rate is generally better.

4 · Team context, not ranking inputs

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.
