8. Golden State Warriors (2015)
This was the greatest regular-season team of the 21st century. The Warriors came in the 2015-16 season as defending champions. On paper, they were even better than their title-winning side. They broke an incredible number of records throughout the season. Meanwhile, players like Stephen Curry and Klay Thompson were on top of their game. They even put together one of the NBA’s longest winning streaks ever.
The Warriors won 24 games in a row and crushed the Western Conference. Everybody favored them to win the NBA Finals but the Cleveland Cavaliers had other ideas. LeBron James and his team were inspired as they upset the Warriors (via New York Times). It just goes to prove that the best teams don’t always enjoy a happy ending. In the end, James tore up the script and rewrote history.
