What is the best start in NBA history? Cleveland Cavaliers remain undefeated originally appeared on NBC Sports Bay Area
Talk about a perfect start.
With the 2024 NBA regular season nearly three weeks old, the Cleveland Cavaliers remain undefeated, having won their first 12 games. Their latest victory came Monday with a 119-113 road win over the Chicago Bulls, making them just the eighth team in league history to start a season 12-0.
Of the seven previous teams to do so, five went on to advance to the NBA Finals that season, with two 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.
