Most Wins in NBA Season (Golden History)

most wins nba

Every few seasons, we witness one or two NBA teams simply dominate the league. 

You’ll know, because the basketball pundits will point out that these teams have stringed together many wins in a row.

They’ll also bring up the fact that they haven’t lost back-to-back games in a while and keep blowing their rivals out of the water.

In fact, powerhouse teams are so common now that the record for most season wins was challenged or broken five times since the 90s. 

The original benchmark to beat was a 69-13 record set by the 1971-72 Los Angeles Lakers. Now that we know that this record was broken, who now owns the record for 70+ wins? 

Which NBA team has the most wins in a season?

The Golden State Warriors hold the record for most wins in an NBA season with 73. The Warriors accomplished this feat in the 2015-16 season, finishing with a 73-9 team record and 0.890 winning percentage. They surpassed the previous record held by the Chicago Bulls since the 1995-96 season with 72 wins.

As a note, the Bulls finished the season at 72-10 and a 0.878 winning percentage. The Warriors and the Bulls are the only two teams to reach 70+ wins in a season

Unfortunately for the Warriors, they did not manage to win the championship in 2016. 

While they made it to the finals, the Warriors lost to Lebron James and the Cleveland Cavaliers. The Cavs were able to come back from a 3-1 series deficit and win three consecutive games to win 4-3.

And for those wondering, the 72-10 Bulls team, led by Michael Jordan, won the Larry O'Brien NBA Championship Trophy in 1996. They won the series 4-2 against Shawn Kemp and the Seattle Supersonics.

Most consecutive Wins in NBA Season

Since we were on the topic of most wins in a season, which team owns the record for consecutive victories? 

While you’d figure it was the 2015-16 Warriors, they are 3rd on the list or, perhaps 2nd depending on if you make an exception.

What I mean is that the Warriors started off the 2015-16 with 24 consecutive wins, which would land them in third place.

But they won their last 4 games in the season prior (2014-15), which would have them sitting at 28 consecutive victories. Again, that would rank them #2 if we included interseason streaks.

In actuality, the record belongs to the 1971-72 Lakers with 33 consecutive wins.

The next best team was set by the 2012-13 Miami Heat, led by Lebron James and Dwayne Wade. The Heat managed a 27-game winning streak that year.

We could argue in favor or against the Warriors owning 2nd spot but remember that the Warriors playoff record was exempt from the count.

For the purists and the Lebron James superfans, there is no doubt who owns 2nd place – the Miami Heat.

Lastly, there are only 6 teams that cracked the 20+ win streak in the history of the NBA. Make sure to check out the full list here for more info.

Winningest Team in NBA history

As for the winningest team in NBA history, we can look at it from two perspectives. The team with the most total wins, without question, are the Boston Celtics - with 3,513 Wins (prior to the start of the 2022-23 NBA season). 

However, the San Antonio Spurs have the greatest PCT (win percentage) record of any storied NBA franchise at 0.611 (or 61.1%). 

But the Spurs have only won 2,261 games, having played many less games than the Celtics overall. 

The Los Angeles Lakers hold the second spot for both wins (3,460) and PCT (0.592).

NBA Team with the worst losing record

The Philadelphia 76ers own the record for the most losses in a season. They went an embarrassing 9-73 in the 1972-73 season. That record amounts to a dismal 0.110 winning percentage on the season. 

But while the 76ers lost the most games in a season, the Charlotte Bobcats own the record of least wins in a season. Back in the shortened 2011-12 NBA season, the Bobcats finished with a 7-59 record.

Their (Bobcats) winning percentage was an all-time worst at 0.106. 

The Bobcats were on pace for 8.7 wins had the league played the standard 82-game season. It’s quite possible they would have finished worse off than the 1972-73 Philadelphia 76ers.

Unfortunately, we’ll never know how that would have played out.

NBA Team with the worst losing streak

As for the worst losing streak, that belongs to the Philadelphia 76ers at 28. Their streak spanned both the 2014-15 and 2015-16 seasons.

The longest losing streak in one season is not too far behind at 26 games. This record is shared between the 2010-11 Cleveland Cavaliers and the 2013-14 Philadelphia 76ers.  

Unfortunately, the 76ers had a rough stretch during the early 2010’s and a rough go a few decades prior.

But no worries though, they’ve been a solid team since the 2017-18 season. Let’s hope the 76ers can turn their fortunes around and earn a 4th championship title. 

Final Thoughts

When it comes to professional team sports, my belief is that the NBA is the only league where team records can likely be broken. 

My theory is that compared to leagues like the NHL (hockey), NFL (football) and MLB (baseball), NBA teams have the highest concentration of talent. 

That is, NBA teams need only to recruit three superstars to create a super team since the active roster limit is set to 15 players per season.

Furthermore, your team stars can end up playing most of each game.

Meanwhile, the active roster in the NHL is made up of 23 players, which hinders the capability of creating a super team.

To complicate matters further, your best offensive NHL player will play a third of each game at most.

The active roster count for both the NFL and MLB are even higher. What may benefit MLB teams is the fact they don’t have a hard salary cap in place.

The best markets can literally pay their way to a superstar team. Examples include the New York Yankees, Boston Red Sox, Los Angeles Dodgers and so forth.

You can take another approach to this – NBA player contracts.

The NBA sets a limit of five years to individual contracts, with the 5th year as a player option. 

If you want to read more on NBA contract lengths and salaries, make sure to check out my blog post on the Average NBA Salary.

This means that players, more than any other league, will become free agents most often.

And with that, although unethical, players can easily join forces to create a super team.

We can ignore the NFL since the average player career is 3.5 years.

But players in the NHL and MLB can sign much longer contracts, which is mostly guaranteed throughout. 

The MLB does allow for club options at the tail end of a contract. That is, if the player is performing below expectations, their club can choose to terminate the contract with minimal penalty. 

In the end, the verdict is that you have a better chance witnessing dynasties formed in the NBA than any other “big 4” league.

The last championship three peat occurred in the NBA as well.

With that said, I’d bet that another NBA team will challenge the record for most wins in a season soon enough.
