These NBA teams had the best starts to an NBA season, going on double-digit winning streaks to start a season undefeated.

Talk about a perfect start.

With the 2024 NBA regular season more than three weeks old, the Cleveland Cavaliers remain undefeated, having won their first 15 games. Their latest victory came Sunday with a 128-114 home win over the Charlotte Hornets, making them just the fourth team in league history to start a season 15-0.

The three previous teams to do so all went on to make the NBA Finals that season, with one winning the championship, per NBA.com.

Impressive as the Cavs' start has been, they still have a long way to go to match the league's record for most consecutive victories to open a season.

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