The days of one-team dominance in the NBA appear to have come and gone, for the time being. Three of the four past league champs entered the postseason with title odds of +850 or higher, speaking to the newfound parity in the 30-team association. It’s a trend to watch for folks using the best US betting sites to place an NBA futures wagers as the next season looms.
USBettingReport.com wanted to know which teams were the 10 biggest underdogs (according to their odds at the beginning of the playoffs) to win an NBA title in the past 40 years. This data was pulled from SportsOddsHistory.com.
10 Biggest Underdog NBA Champs Since 1985
| Year | Team | Odds |
|---|---|---|
| 1995 | Houston Rockets | +1800 |
| 2011 | Dallas Mavericks | +1800 |
| 2022 | Golden State Warriors | +1000 |
| 2023 | Denver Nuggets | +1000 |
| 2019 | Toronto Raptors | +975 |
| 2021 | Milwaukee Bucks | +850 |
| 2004 | Detroit Pistons | +700 |
| 1994 | Houston Rockets | +600 |
| 2006 | Miami Heat | +500 |
| 2016 | Cleveland Cavaliers | +475 |
Several Recent Champions Defied Odds
The 2022 Golden State Warriors and 2023 Denver Nuggets each entered the playoffs with +1000 title odds. The 2021 Milwaukee Bucks were at +850 and the 2019 Toronto Raptors sat at +975 when they began their title run.
The only other team since 1985 to enter the postseason with odds in the four-digit range came in the past two years, pointing out to customers at US sports betting apps that this trend might be the exception more than the new rule.
Which Team Really Was Biggest Underdog?
Again, Houston in 1995 and Dallas in 2011 share the distinction of having the longest pre-playoff odds for any NBA champion. But you could argue that neither was a true “underdog” winner. The Rockets had won the title in 1994; the Mavericks lost in the NBA Finals in 2006 and had reached the postseason in each of the 10 seasons before they finally won it all in 2011.
The Warriors’ 2022 team was also a bit of an abnormality, coming on the heels of three NBA championships in seven years under Steve Kerr’s leadership.
That leaves the 2023 Nuggets as perhaps the league’s most unlikely (or underdog) champion at NBA betting sites.
Denver had never made it to the NBA Finals before the team’s run last season. The Nuggets lost the Western Conference final in 2009 and 2020 and were ousted in the West semifinals several times, most recently in 2021.
That was until Michael Malone’s bunch ran the table a year ago, knocking off the Minnesota Timberwolves, Phoenix Suns, Los Angeles Lakers, and Miami Heat on the way. The Nuggets had a combined record of 16-4 in those postseason contests.
Many might argue about which NBA team was the “biggest underdog” in league history since 1985 to win it all, but one can definitely make an argument that Malone and company fit the bill.
