PHX was also found the same year when MIL was found, that is 1968. They have played amazingly in several seasons. Season 2021 was when PHX made it to the finals. However, they had a hard time which led them towards losing the final game.
Since 1968 PHX has never won an NBA Title. This was their third time playing a final, but they were not able to win. It means they have been their conference champions 3 times.
