The Last team from the Western Conference to win a championship not in California or Texas was the Seattle SuperSonics in 1979

This is the most recent time that a Western Conference team not based in Texas or California has won an NBA title, and the last of only two occasions alongside the 1976–77 Portland Trail Blazers when a team from the present-day Northwest Division has won the league title, which is by 27 years the longest league championship drought for any division of the four major North American sports leagues. [note 1] Since then, the following Western teams have gone on to win an NBA title: the Los Angeles Lakers (eleven times), the San Antonio Spurs (five times), the Golden State Warriors (four times), the Houston Rockets (twice), and the Dallas Mavericks (once). The remaining twenty-one titles since 1980 have been won by Eastern Conference teams.

Will that stat ever change in the near future?
