🏀 Every NBA season since 1947

Highest rating at the end of the season, which is not the same as champion and disagrees 28 times. Reading across, a colour that holds for four squares is a dynasty and a wall of different colours is a decade nobody owned. A franchise with no stored colour keeps the neutral border rather than being assigned one.

The rating is where a team finished the season, so this is not hindsight about a bad night: it is the league's best side over a whole year losing a short series. That is the sport working as designed, and the list is what a seven-game round costs the better team.
