What is the best start in NBA history? Cleveland Cavaliers remain undefeated

Talk about a perfect start.

With the 2024 NBA regular season nearly three weeks old, the Cleveland Cavaliers remain undefeated, having won their first 11 games. Their latest victory came Saturday with a 105-100 win over the Brooklyn Nets, making them just the 12th team in league history to start a season 11-0.

Of the 11 previous teams to do so, six went on to advance to the NBA Finals that season, with three winning the championship, per NBA.com.   

Impressive as the Cavs’ start has been, they are still only halfway to matching the league’s record for most consecutive victories to open a season. 

Here’s a look back at the NBA’s best unbeaten starts.

What’s the best start in an NBA season?

It didn’t seem like the 2015-2016 Golden State Warriors would ever lose.

They won their first 24 games of the regular season, breaking the previous record of 15-0 starts set by the 1993-1994 Houston Rockets and 1948-1949 Washington Capitols.

What is the best record in NBA history?

The 2015-2016 Warriors also went on to set an NBA record for wins in a season, finishing 73-9. That topped the previous record of 72-10 set by the 1996-1997 Chicago Bulls.

Unlike the Bulls, however, the Warriors did not win the championship. They surrendered a 3-1 series led in the NBA Finals to LeBron James and the Cleveland Cavaliers and lost in seven games.

What is the longest winning streak in NBA history?

The 1971-1972 Los Angeles Lakers hold the record for longest winning streak in NBA history at 33 games. Jerry West and Wilt Chamberlain guided the team to a 69-13 finish and an NBA championship.

The 2012-2013 Miami Heat came closest to reaching the record, winning 27 straight games during their championship season.

The only other NBA teams to win 20 or more straight games in a single season are the 2015-2016 Golden State Warriors (24 games), the 2007-2008 Houston Rockets (22 games) and the 1970-1971 Milwaukee Bucks (20 games).
