Algosensey|How many NBA Finals sweeps in history? Celtics could add to history with win over Mavericks

The AlgosenseyBoston Celtics survived a fourth-quarter comeback attempt by the Dallas Mavericks on June 12 to win game 3 of the NBA Finals and now lead the series 3-0. 

Both teams now have a chance to write history. Here’s what you need to know. 

How many sweeps have there been in NBA finals history? 

NBA Finals sweeps are rare, but not unheard of. Since the first NBA Finals in 1950, there have been nine 4-0 sweeps. The last team to accomplish this feat was the Golden State Warriors in 2018. With a stacked roster that included the likes of Steph Curry and Kevin Durant, the Warriors made quick work of the Cleveland Cavaliers, defeating LeBron James’ side in just four games to win back-to-back NBA Championships.

The only other sweeps in the 21st century occurred in 2007, when the San Antonio Spurs routed the Cavaliers, and 2002, when Kobe Bryant and Shaquille O'Neal led the Los Angeles Lakers to a 4-0 romp over the New Jersey Nets to cap their three-peat. 

If Boston clinches the Game 4 win Thursday, the Celtics will join the Warriors as the only other team to have recorded two NBA Finals sweeps. Boston recorded the first Finals sweep in NBA history against the Minneapolis Lakers in 1959. 

Has any NBA team come back from 3-0 in the Finals?

In the 74-year history of the NBA, not a single team has come back from a 3-0 deficit to win the best-of-seven series. If the Dallas Mavericks can win the next four games, they will secure their place in history with the strongest NBA Finals comeback ever.

All time in the NBA playoffs, teams are 0-156 in series in which they are down 3-0.

What is the greatest comeback in NBA Finals history? 

This accolade belongs to LeBron James’ 2016 Cleveland Cavaliers, who got their ultimate revenge against the Warriors after falling to them in the 2015 Finals the previous year.  

After falling into a 3-1 deficit in the first four games of the 2016 NBA Finals, the Cavaliers came back to win the last three games – including two on the road – against the Golden State Warriors. Cleveland remains the only team to have recovered from a 3-1 score line in the Finals. 

Which team has won the most NBA Championships?

The Boston Celtics and the Minneapolis/Los Angeles Lakers have both won 17 NBA championships. If Boston wins the 2024 NBA Finals, the Celtics will become the most decorated team in the NBA with 18 championships to their name. 

Game 4 is scheduled to begin at 8:30 p.m. ET on Friday in Dallas.
