How much parity is there in the NBA? Will it stick? The how and why of the current era
Welcome to our new era of NBA parity, where one team in each conference is favored by Vegas to lap the field by several games.
Wait ...
what? Yes, its true: Despite the seeming increase in parity over the last several years, and some structural changes that make it seem likely to continue, the Boston Celtics and Oklahoma City Thunder begin the year as heavy favorites in each conference.
Advertisement So where are we, exactly, and how much parity is there? The discussion of parity in the NBA gets pretty nuanced once you start rifling through the weeds, and the cognitive dissonance of my introductory sentence is a perfect example.
Lets start at the top and try to parse out what is happening right now, why its happening and whether its likely to continue.
GO DEEPER The NBA has entered a new era of parity.
How did we get here and what's next? What do we mean by parity? Whether you think there is parity now, and how much, turns first on what exactly you mean by parity.
On one hand, talking about parity seems a little ridiculous when the Celtics just finished breaking the NBA, rolling to the third-highest scoring margin of the last half century while winning 80 of their 101 regular-season and playoff games and cruising to the championship.
Well circle back to them and to a budding dominant West team in the Thunder in a little bit.
However, by a few different measures, we certainly have had parity for the last half decade or so.
Thats especially true if youre talking about dynastic parity, the idea that one or two teams arent ruling over the league every year.
In the middle of the last decade, we had the Golden State Warriors and Cleveland Cavaliers play each other in four consecutive NBA Finals, but since then, weve been near the mathematical limit of parity as far as the playoffs are concerned.
In that time, weve seen six different champions a new one each year and nine different finalists.
Another five have made the conference finals, giving nearly half the league a taste of late-May basketball in a little more than half a decade.
And while 14 teams have made it that far at least once, only two teams (Boston and Miami ) have made the conference finals more than twice.
Individually, nearly every franchise has had a rollicking roller-coaster ride of ups and downs (well, except Detroit ).
The Warriors, for instance, went from the 2019 finals to being the worst team in the league in 2019-20, then bracketed a championship season and a second-round playoff run with two other trips to the draft lottery.
Thats quite a ride.
Advertisement Theyre not alone.
The Heat played in four Play-In games and only had a top-four seed in the Eastern Conference once but made two NBA Finals and won eight East playoff series in that time.
The Atlanta Hawks and Minnesota Timberwolves each were good enough to make a conference finals and bad enough to win the draft lottery in that same span.
The Dallas Mavericks made a conference finals and an NBA Finals in a three-year window; in between, they missed the Play-In entirely.
Weve also had more evenness in terms of regular-season dominance .
Before Boston in 2024, we had six straight champions that failed to clear 60 regular-season victories*, and a few that were nowhere close.
Before the Celtics this spring, we had three straight champions with the lowest win total for a champion since Miami (52) in 2006: Denver in 2023 and Golden State in 2022 had 53, and Milwaukee in 2021 pro-rated to just 52.4 (that season featured 72 games).
(*The Lakers pro-rated to exactly 60 in the COVID-19-pandemic-shortened 2019-20 season, although they might have let their foot off the gas if theyd been required to play the final 11 games.) Concomitant with this has been the trend of a fat middle of teams winning between 40 and 52 games.
It doesnt really seem mathematically possible, but 17 of the leagues 30 teams fit that description last season; a year earlier, it was 16.
That, as much as anything, might boost the perception of parity, as it generates a Lake Wobegon-ish feeling that every team is above average.
Dreaming bigger, when two-thirds of the league falls into So youre telling me theres a chance...
territory, it starts to feel like the NFL .
Finally, theres the example of playoff parity .
The NBA, historically, has been an extremely chalky league when it comes to the postseason, and to an extent, that has still held 44 of the past 45 champions have been seeded third or better, had at least a plus-3 scoring margin and won at least 52 games in the regular season.
Advertisement However, something funky has been going on in the second round.
In the last six postseasons of this post-Cavs-Warriors era, the team without home-court advantage has won 14 of those 24 second-round series, including upsets of teams that won 64 games (Dallas over Phoenix in 2022) and a pro-rated 63 (Miami over Milwaukee 2020).
That has underscored a more general randomness in the playoffs.
The last half decade has seen a No.
8 seed and two No.
5 seeds make the finals, and two No.
7 seeds and another No.
5 seed make the conference finals.
Last springs Dallas-Minnesota West finals marked the fourth time in five years that neither of a conferences top two seeds made it past the second round.
On the other hand, theres the counterexample of what we might call struggle parity .
Remember, parity isnt just about the top of the league; its also about the bottom.
And on that front, we havent had much parity at all.
The 2023-24 Pistons set an NBA record with 28 consecutive losses, and both the Pistons (14-68) and Wizards (15-67) had a worse record than any other team since the 10-72 Sixers in 2015-16 .
The Portland Trail Blazers , Charlotte Hornets and San Antonio Spurs joined them in the 60-loss club last season; seven teams lost at least 55 games.
Now you know where that fat middle comes from.
The NBA is a zero-sum game where the wins and losses need to add up to 1,230 every year; you cant have 20 teams win 40-plus unless the 10 that dont are pretty awful.
An economist might say the leagues Gini coefficient still doesnt look so great when you account for the misery at the bottom.
So, to sum up where we stand: Revolving champions, less in-season dominance, more playoff randomness, a fat middle and a destitute bottom quarter of the league.
Four of those five things youd describe more as parity than not.
So the trend line seems real.
Why is this happening? Theres a tendency to blame the new collective bargaining agreement for literally everything, and it may end up being a factor in prolonging whatever parity already exists.
But remember, weve had only one season under the new rules, and with Boston jogging to a title, it arguably featured the least parity of the previous five.
Advertisement Its easy to look back with a clear eye at the greatest era of parity in the league in the mid-to-late 1970s to understand why we might be in the current phase.
The best players from that era either had insufficient support (Kareem Abdul-Jabbar), were constantly injured (Bill Walton) or were playing in another league entirely (Julius Erving).
Once the Celtics, Lakers and Sixers united multiple superstars under one roof, parity disappeared for the 80s.
You can make the same case for the current era.
Toronto , Denver, Golden State and Milwaukee were one-superstar outfits; Boston has multiple stars but no top-five player in the league.
Only the 2020 Lakers fit the mold of a champion spearheaded by two elite stars.
Since then, theyve been hamstrung by the same rest-of-roster issues Abdul-Jabbars teams had in the 1970s.
Theres a second issue, however, nobody talks about: The super teams failed.
It wasnt that the league wouldnt let you build them; it was that the teams that succeeded in doing so still didnt win with those Lakers being a lone exception.
The Brooklyn Nets tried to put Kyrie Irving , James Harden and Kevin Durant together and were a pinkie toe away from pulling it off, but the plane never flew after 2021.
The LA Clippers got one healthy postseason and bonked it away in a collapse in the NBA bubble.
Durant walked away from a super team in Golden State, and Irving arguably did the same in Boston.
And in 2023-24? The star talent in the league was so distributed that the 10 players who made first and second team All-NBA came from 10 different franchises.
Thats a far cry from the dynastic cores the Heat and Warriors built in the previous decade.
Will it continue? Thats where the CBA comes in, because it should have a big impact on dynastic parity in particular.
Lets back up a little and talk about the CBA, and start from this point: Every CBA isnt just between the owners and players it also governs the rules between all 30 owners.
In the 2023 negotiation, small-market owners extracted an important piece of flesh.
The rules for the highest-spending owners became much harsher, in an effort to legislate away the financial advantage teams such as the Clippers and Warriors were lording over their lighter-spending counterparts.
Weve already seen much discussion about the impacts of the second apron the payroll threshold set this season about $18 million above the luxury tax level and in particular how it disincentivizes teams to stay above it for more than two seasons in a five-year span.
Less discussed but equally relevant is a much harsher repeater penalty for teams who go into the tax three times in four years.
That can pack a financial wallop for some clubs even before a second-apron penalty would hit.
For example, Boston is headed for a staggering tax bill in 2025-26 if it doesnt significantly pare down salary, and that will incentivize the Celtics to cut payroll even before any second-apron penalty would hit a year later.
Advertisement Ironically, however, it might produce less parity in the short term.
If only a couple of teams can manage to put together an elite roster under the increased roster-building constraints of the CBA, while everyone else tops out at pretty good even if they have MVP-caliber building blocks ...
well, thats how you might get a situation that looks an awful lot like this coming season.

The story of the greatest plays in NBA history.
Boston and Oklahoma City masterfully crafted together rosters that still work under the new rules thanks in part to rare circumstances: Boston by just beating the new-CBA buzzer with 2023 trades for Kristaps Porzingis and Jrue Holiday , and Oklahoma City by having much of its top talent on favorable rookie contracts.
Every one else, it seems, is left to choose between being too top-heavy or too star-deprived.
Even the Celtics and Thunder, however, will have clamps on their most dynastic ambitions because of the apron and repeater rules.
Under this CBA, most teams are likely to find themselves pushing their chips in for two-year windows of true contention, then retrenching to get below the second apron before having another go at it.
In the leagues eyes, thats a feature, not a bug.
The hope is that teams have to make difficult roster choices, that top-heavy teams with three superstars are mostly a thing of the past and that the result leads to more competitive balance.
On many levels, that seems to be happening: The fat middle of pretty good teams and the relatively quick turnover of champions both seem likely to stay with us.
The playoff randomness? Well see if that isnt actually also random, or if it has staying power; Im not fully sold yet.
In any one season, however, the concept of parity may seem a bit more elusive.
At the bottom end, it also cant stop a team like last years Pistons from running into walls.
More importantly to most fans, the larger framework cant stop a team such as Boston from putting together a dominant two-year run, or an up-and-comer such as the Thunder from running away and hiding from the rest of the West (as it seems may happen in 2024-25).
So enjoy our brave new CBA world, everyone.
Were still learning all the impacts and consequences, both intended and unintended.
But one of them seems to be that, whatever your definition of parity, the recent trend toward more of it is likely to drag on a while longer.
