Best NBA Season Record: Which Teams Truly Dominated the League's History?

When people ask me about the most dominant NBA teams in history, my mind doesn’t immediately jump to flashy one-off championship runs—I think about sustained excellence. As a longtime basketball analyst, I’ve always been fascinated by teams that didn’t just win, but dominated over the long haul. Take the Golden State Warriors’ 73-9 season in 2015-16, for example. That record broke the 1995-96 Chicago Bulls’ legendary 72-10 mark, and yet, in my view, it’s a bittersweet achievement. Why? Because they didn’t seal the deal with a championship. That’s the thing about dominance—it’s not just about regular-season brilliance; it’s about translating that into postseason glory.

I remember watching the 1995-96 Bulls, and honestly, nothing since has quite matched that aura. Michael Jordan, Scottie Pippen, and Dennis Rodman weren’t just playing basketball; they were executing a masterplan. They went 72-10, and then bulldozed through the playoffs with a 15-3 record. That’s a combined 87-13 run—absurd, by any measure. And here’s a stat that still blows my mind: they had a point differential of +12.2 per game. In today’s pace-and-space era, no one has consistently touched that. The Warriors came close in their 73-win campaign, but losing the Finals to the Cavaliers, as historic as LeBron’s comeback was, left a stain on their résumé.

But let’s rewind even further. The 1971-72 Los Angeles Lakers, led by Wilt Chamberlain and Jerry West, set a benchmark that stood for over two decades: 69 wins and a 33-game winning streak. I mean, 33 games! In today’s load-management culture, that’s almost unthinkable. They capped it off with a title, sweeping the Knicks in the Finals. That Lakers squad was a machine—they played with a relentless pace and efficiency that would make modern analysts drool. Their record stood until the Bulls’ 72-win season, and to me, that’s the mark of true dominance: when your achievements resonate across eras.

Now, I’ll admit, I have a soft spot for the San Antonio Spurs. People often overlook them because they never notched a 70-win season, but their consistency was otherworldly. From 1999 to 2014, they won five titles and made the playoffs every single year. In the 2015-16 season, they went 67-15—arguably one of the most underappreciated campaigns ever. And yet, they bowed out in the second round. It’s a reminder that regular-season dominance doesn’t always guarantee playoff success. Which brings me to a point I often stress: context matters. The 2008-09 Cleveland Cavaliers, for instance, went 66-16 behind LeBron’s heroics, but fell short in the Conference Finals. Sometimes, a single superstar can carry a team to incredible heights, but basketball, at its core, is a team sport.

Speaking of teams, let’s talk about the 1985-86 Boston Celtics. They went 67-15, playing in one of the toughest eras physically. Larry Bird, Kevin McHale, and Robert Parish—that frontcourt was just brutal. They finished with a 40-1 home record, which, frankly, is a stat that feels almost made up. I’ve always believed that home-court dominance is a huge indicator of a team’s mental toughness, and the Celtics of that era had it in spades. They swept through the playoffs until the Finals, where they beat the Rockets in six. That kind of swagger—knowing you’re unbeatable at home—is something you rarely see today.

In contrast, the modern game has given us teams like the 2020-21 Utah Jazz, who racked up 52 wins in a shortened season and had the best record in the league. But did anyone truly see them as dominant? I didn’t. They flamed out in the second round, and that’s the tricky part about evaluating greatness—it’s easy to pile up wins in the regular season, but the playoffs expose every flaw.

Which brings me back to the Warriors. Their 73-win season was a marvel of modern basketball—unselfish ball movement, historic three-point shooting, and a deep roster. Steph Curry’s unanimous MVP season was a joy to watch. But here’s my hot take: as impressive as it was, I don’t rank it above the Bulls’ 72-win year. Why? Because the Bulls finished the job. They imposed their will from October to June, and that, to me, is the ultimate measure of dominance.

So, what does it take to truly dominate the NBA? It’s not just about racking up wins; it’s about legacy. The Bulls, the Lakers, the Celtics—these teams didn’t just set records; they defined eras. And as much as I admire the Warriors’ run, I can’t help but feel that without the championship, it’s like a beautiful painting with an unfinished corner. Dominance is about completeness.

Looking ahead, I wonder if we’ll ever see another team challenge these records. With player mobility at an all-time high and the regular season often treated as a preamble, it seems unlikely. But that’s what makes these historic runs so special—they’re not just numbers in a record book; they’re stories of teams that, for one glorious season, were nearly perfect. And as a fan, that’s what I’ll always cherish.
