There’s only one undefeated team left in the NBA this season, and it might come as a bit of a surprise. After a 119–113 win over the Chicago Bulls on Monday, the Cleveland Cavaliers are 12–0 on the year and the only team in the league with fewer than two losses.

Cleveland is now the 14th team in league history to start a season with ten straight wins, and nothing about it feels like a fluke. The Cavs moved to 11-0 after beating the Brooklyn Nets on Saturday night.

The win over the Bulls marked the second straight comeback victory for Cleveland. The Cavs undefeated start seemed over Saturday night against the Brooklyn Nets, who led by 14 points late in the 3rd quarter. Cleveland was still trailing by seven with 4:24 left in the game when they went on a 10-0 run to take the lead. They won 105-100.
