During the 1995-96 season, the Chicago Bulls went on an insane run in which they went 72-10 and won the NBA championship. It was a massive accomplishment as they picked up the best record in NBA history while also picking up a fourth title. Twenty years later, the Golden State Warriors broke the Bulls regular-season record by going 73-9. Things didn't work out so well for the Warriors in the end as they ended up losing to the Cleveland Cavaliers in the NBA Finals.
The one parallel between both of those teams was Steve Kerr. Kerr was a point guard on the Bulls and was the coach of the Warriors. During the most recent episode of "The Last Dance," Kerr explained that the better of the two teams was, indeed, the 72-10 Bulls.
These comments provide closure to a debate fans have been having since 2016. While 73 is better than 72, the true barometer of a successful team is whether or not you can win the championship, and the Warriors weren't able to do that. By default, you would have to give the edge to the 72-10 Bulls.
All you Warriors fans are probably in shambles right now but that's okay. You won three championships in four seasons and that's all that matters.
