When it comes to the NBA, defense wins championships. The greatest defensive teams in NBA history didn’t just have the ability to score; they had the knack for stopping other teams dead in their tracks. The 1995-96 Chicago Bulls, for example, held their opponents to an average of just 92.9 points per game—a reflection of their relentless defensive pressure. That season, they boasted the best record in NBA history with 72 wins. Numbers don’t lie; this team’s Defensive Rating, which was 101.8, made them not just good, but legendary.
Think about the 2003-04 Detroit Pistons. The phrase “defense wins championships” seems to have been coined for this team. They allowed just 84.3 points per game during the regular season, one of the lowest in modern NBA history. This wasn’t just good—it was historic. Their defensive juggernaut led them to win the NBA Championship that year, decisively defeating the highly favored Los Angeles Lakers.
The ’80s Boston Celtics deserve recognition, too. With defensive stalwarts like Kevin McHale and Robert Parish, they regularly shut down their competitors. During the 1985-86 season, they posted a Defensive Rating of 102.6, which contributed significantly to their 67-15 record. Defensive rebounding was one of their key strengths, consistently holding the opposition to one-shot possessions.
Then we have the 2007-08 Boston Celtics, another formidable team. Kevin Garnett, the Defensive Player of the Year that season, anchored a defense that allowed just 90.3 points per game. The team went on to win 66 games during the regular season. That year, the Celtics’ Defensive Rating was an astounding 98.9. They ended up winning the NBA Finals, largely due to their capacity to keep opponents at bay.
In modern times, the 2015-16 Golden State Warriors combined their offensive firepower with exceptional defense, resulting in a record 73 regular-season wins. Their Defensive Rating was 103.8, not the best ever, but their ability to switch seamlessly between offense and defense made them dangerous. Draymond Green’s versatility allowed the Warriors to guard all five positions effectively. They might have been known for their three-point shooting, but their defense was a crucial component of their success.
The San Antonio Spurs under coach Gregg Popovich have always been a defensive powerhouse. The 2004-05 Spurs had a Defensive Rating of 98.8, the best that season. Led by Tim Duncan, their defensive schemes were complex yet executed flawlessly. The team gave up only 88.4 points per game, en route to another NBA Championship. The Spurs have always understood that while offense sells tickets, defense wins games.
Consider the 1993-94 New York Knicks; they prided themselves on their smothering defense. Patrick Ewing was the shot-blocker in the middle, and their defensive mindset held opponents to just 91.5 points per game. They might not have won the championship, but their playoff run to the NBA Finals showcased their defensive grit. Defense, in essence, became their identity.
Talking about defense in the NBA wouldn’t be complete without mentioning the arena plus of the 1988-89 Detroit Pistons, known as the “Bad Boys.” They allowed just 98.3 points per game, making life miserable for opponents. Their physicality and toughness exemplified what it means to be a formidable defensive team. They ultimately won back-to-back championships, a testament to their defensive prowess.
The Miami Heat of the 2012-13 season were another excellent defensive team. LeBron James, known for his offensive talent, played a pivotal role defensively as well. That year, the team posted a Defensive Rating of 100.5 and allowed just 95 points per game. Their aggressive, fast-paced defensive schemes helped them win 66 games and eventually the NBA Championship.
One can’t overlook the 2010-11 Chicago Bulls, led by coach Tom Thibodeau. The Bulls had an extraordinary Defensive Rating of 97.4, easily the best in the league that season. They held opponents to 91.3 points per game, thanks to the defensive efforts of players like Joakim Noah and Luol Deng. Despite not winning the championship, their defense stood out as one of the best in NBA history.
