The top 8 preseason underdogs to ever win an NBA championship

When it comes to the game of basketball, all 30 NBA teams start the season with one goal—hoisting the Larry O’Brien Championship Trophy high above their heads, as the color-coordinated confetti rains over them. Since the 1984-85 season, just eight teams have won the NBA title after receiving preseason odds of 10-1 or greater. The other 30 champions all posted preseason odds of 9-1 or better, and 16 of those 30 had odds of 3-1 or better.

Three times the NBA champion won the crown after receiving even odds in the preseason. The Chicago Bulls did so in Michael Jordan’s penultimate season with the franchise, while the Golden State Warriors did so back-to-back from 2016-18, in what many long-suffering Bay Area basketball fans remember as the #WeBelieve run.

In each instance, these teams defied the odds and walked away with the trophy lifted above their heads. How did they get there? Who had the best squad? OLBG ranked the eight biggest preseason underdogs to win the NBA championship since the 1984-85 season using data from Basketball-Reference.com. Besides title odds, the data on this list includes each team’s win/loss over-under as posted preseason and their actual regular season record.

#8. 2007-08 Boston Celtics

– Championship odds: 10-1

Led by head coach Doc Rivers, the 2007-08 Celtics roster featured three future Naismith Memorial Basketball Hall of Fame inductees—Ray Allen, Paul Pierce, and Kevin Garnett. The construction of the team’s roster that season resulted in general manager Danny Ainge being named NBA Executive of the Year after the Celtics won 24 games during the 2006-07 season.

The Celtics, who led the NBA in wins for the 2007-08 campaign, would face their long-time rival the Los Angeles Lakers in the Finals. In a hard-fought battle, Boston would defeat a Los Angeles team that included Pau Gasol and the late Kobe Bryant, 4-2 in the series, to capture what would be the Celtics’ first championship since 1986.

Larry Brown coached the Pistons through a playoff journey that saw the team defeat the Nets in seven games in the Eastern Conference Semifinals. The Pistons would then need six games to top the Indiana Pacers in the conference finals before a 4-1 series win over the Lakers in the Finals.

#1. 2014-15 Golden State Warriors

– Championship odds: 28-1
– Win/loss over-under: 52.5
– Regular season record: 67-15

The beginning of what would be a dynasty began with another first-year head coach in Kerr, who started his tenure in Northern California with a 10-2 record—the best start in franchise history. The Warriors would later have a stint during the season in which it won 16 straight.

The Warriors’ ability to string together strong performances was the result of a dynamic offense led by Stephen Curry—the 2015 NBA MVP. The Warriors also benefited from a roster that included Harrison Barnes, Draymond Green, Andre Iguodala, and Klay Thompson. Veterans Andrew Bogut, Leandro Barbosa, and Shaun Livingston also rounded out the team.

Golden State swept the New Orleans Pelicans in the first round of the playoffs before defeating the Memphis Grizzlies in six games. The Warriors would need five games to topple the Rockets in the Western Conference Finals before a 4-2 series win in the NBA Finals against the Cleveland Cavaliers. Golden State’s title came after the team didn’t have a 2014 draft pick.
