Since one year after the award was first awarded in 1956, only five teams have ever won an NBA Championship without a player who won or would win a regular-season MVP award.
1975 Golden State Warriors- Ric Barry got close, but never won one
1979 Seattle SuperSonics (RIP)- Dennis Johnson was the Finals MVP, and I can’t recall him ever getting heavy consideration
1989/1990 Detroit Pistons- Isiah never won one.
2004 Detroit Pistons- There’s still a little time, but I sincerely doubt it.
That’s forty-eight out of fifty-three NBA Championship teams and 48/50 for non-Pistons champions.
