The 2026–27 NBA season begins Tuesday with a dramatically different landscape.
LeBron James is wearing a Philadelphia 76ers uniform. Giannis Antetokounmpo is in Miami. Jaylen Brown has left Boston, Kawhi Leonard is back in Toronto, and Ja Morant has a fresh opportunity in Portland.
Meanwhile, the New York Knicks enter the season as defending NBA champions for the first time since 1973, having defeated the San Antonio Spurs in the 2026 Finals.
The offseason produced significant changes in both conferences, but assembling talent and building a championship team are not necessarily the same thing.
Philadelphia and Miami must integrate franchise-altering acquisitions. Boston faces life without Brown. Oklahoma City must compensate for departures from its supporting cast, while San Antonio attempts to turn last season's Finals appearance into a championship.
According to the NBA's annual general manager survey, 50% of respondents selected San Antonio to win the 2027 championship, followed closely by Oklahoma City at 43%.
The Eastern Conference appears considerably more open.
Here is how the biggest moves could reshape the season, which teams are positioned to contend, and our prediction for the 2027 NBA champion.
Philadelphia 76ers: LeBron and Brown Create a Championship Opportunity
No team made a bigger statement this offseason than Philadelphia.
The 76ers acquired Jaylen Brown from Boston in a trade involving Paul George and draft picks, then added LeBron James following his departure from the Lakers.
Suddenly, Philadelphia has an extraordinary collection of talent.
James brings championship experience, playmaking and the ability to control games even at 41. Brown provides athleticism, perimeter defense and proven postseason production.
Tyrese Maxey supplies speed and scoring, while Joel Embiid remains one of basketball's most dominant centers when healthy.
The challenge is obvious: there is only one basketball.
James, Brown, Maxey and Embiid are accustomed to major offensive responsibilities. Coach Nick Nurse must establish a hierarchy without diminishing the strengths of his stars.
Embiid's availability is another critical variable. Philadelphia's championship potential depends heavily on whether he can remain healthy through a demanding postseason.
James' age also makes workload management important.
The 76ers possess enough talent to win the Eastern Conference, but chemistry and health will determine whether their remarkable offseason becomes a championship success.
SportsIn60 projection: 55–27, Eastern Conference finalist.
Miami Heat: Giannis Changes Everything
Miami's acquisition of Giannis Antetokounmpo from Milwaukee was arguably the offseason's most consequential individual move.
The Heat also received Bobby Portis in a blockbuster trade that sent Tyler Herro, Kel'el Ware, Jaime Jaquez Jr. and other assets to the Bucks.
Antetokounmpo gives Miami something few opponents can match: an elite interior scorer who can dominate in transition, pressure defenses at the rim and influence games defensively.
Pairing him with Bam Adebayo creates an imposing frontcourt.
Miami also added Klay Thompson, whose outside shooting could help create space for Antetokounmpo's drives.
The challenge will be offensive balance.
Neither Antetokounmpo nor Adebayo is primarily a perimeter shooter, and opposing defenses will attempt to crowd the paint.
Coach Erik Spoelstra must find lineups that maximize their defensive versatility without sacrificing spacing.
Miami's depth will also be tested following the assets surrendered in the trade.
Still, few teams have a more dangerous defensive foundation.
SportsIn60 projection: 51–31, Eastern Conference semifinalist with Finals upside.
New York Knicks: Defending Champions Face a Different Challenge
New York enters the season with something the franchise spent 53 years pursuing: an NBA championship.
The Knicks defeated San Antonio in the 2026 Finals, ending one of basketball's longest title droughts.
Jalen Brunson remains the foundation of an offense built around intelligent decision-making, shot creation and late-game execution.
Karl-Anthony Towns provides frontcourt scoring, while OG Anunoby supplies valuable perimeter defense.
The Knicks also added Andre Drummond to strengthen their rebounding and interior depth.
Unlike Philadelphia and Miami, New York does not need to establish an entirely new identity.
Its biggest challenge is maintaining the intensity required to defend a championship.
Opponents will spend the season measuring themselves against the Knicks, and the Eastern Conference has become considerably stronger.
The Knicks have the continuity to survive that pressure, but repeating will require another exceptional postseason.
SportsIn60 projection: 56–26, Eastern Conference champion.
Boston Celtics: Tatum Takes Control of a New-Look Team
Boston made one of the offseason's boldest decisions by trading Brown to Philadelphia.
The Celtics received Paul George and draft compensation, reshaping a roster that won the championship in 2024.
Jayson Tatum returns for his first full season following an Achilles injury, and Boston will again depend on his scoring, playmaking and defensive versatility.
George provides veteran experience and another accomplished two-way player, while Derrick White remains an important contributor.
Boston also added Mitchell Robinson and Mike Conley.
The challenge is replacing Brown's athleticism, production and chemistry with Tatum.
George remains talented, but his age and recent inconsistency create uncertainty.
Tatum's health is equally important.
Boston should remain competitive, although the roster looks less formidable than the team that dominated the Eastern Conference two years ago.
SportsIn60 projection: 48–34, second-round playoff contender.
Cleveland and Detroit: Two Teams That Could Disrupt the East
The Cleveland Cavaliers enter the season with Donovan Mitchell and James Harden leading a talented backcourt.
Evan Mobley provides defensive versatility and interior presence, giving Cleveland the personnel to challenge Philadelphia, Miami and New York.
The concern is postseason execution.
Cleveland has assembled strong regular-season teams before, but translating that success into deep playoff runs remains its central challenge.
SportsIn60 projection: 52–30, Eastern Conference semifinalist.
Detroit offers a different kind of threat.
Cade Cunningham has developed into a franchise cornerstone, and the Pistons have assembled a young roster capable of competing physically with established contenders.
Their challenge is sustaining efficient offense against elite playoff defenses.
SportsIn60 projection: 47–35, playoff team with second-round potential.
San Antonio Spurs: Wembanyama's Championship Window Is Open
The Spurs enter the season as the most popular championship selection among NBA general managers.
Victor Wembanyama has developed into one of the league's most influential players, combining elite rim protection with an offensive skill set rarely seen from someone his size.
San Antonio reached the 2026 Finals, demonstrating that its young roster is already capable of competing for a title.
Stephon Castle and Dylan Harper give the Spurs a promising young backcourt, while De'Aaron Fox provides speed and experience.
The organization also added veteran Tobias Harris, strengthening its rotation.
The question is whether San Antonio can take the final step.
Young teams often encounter difficulty maintaining consistency under championship expectations. The Spurs must also manage Wembanyama's workload and ensure their half-court offense remains effective against physical postseason defenses.
Nevertheless, San Antonio has an unusual combination of elite talent, youth and defensive potential.
SportsIn60 projection: 60–22, Western Conference finalist.
Oklahoma City Thunder: Can the Former Champions Reclaim the Title?
Oklahoma City remains one of the NBA's most complete teams.
Shai Gilgeous-Alexander continues to operate at an MVP level, while Jalen Williams and Chet Holmgren provide scoring, size and defensive versatility.
The Thunder's ability to pressure opposing offenses remains a defining strength.
But their supporting cast has changed.
Oklahoma City moved Luguentz Dort and Isaiah Joe during the offseason, losing valuable perimeter defense and shooting.
Those departures could matter during the playoffs, when depth and matchup flexibility become particularly important.
Coach Mark Daigneault must determine whether younger players can assume larger responsibilities without weakening the team's identity.
The Thunder still have the star power, defensive discipline and organizational continuity to win another championship.
Their challenge is maintaining those advantages while replacing proven contributors.
SportsIn60 projection: 59–23, NBA Finals appearance.
Minnesota Timberwolves: LaMelo Ball Joins Anthony Edwards
Minnesota made a major move by acquiring LaMelo Ball from Charlotte.
The addition gives Anthony Edwards another dynamic offensive creator and potentially reduces the burden on him to initiate every important possession.
Ball's passing and transition play could create easier scoring opportunities for Edwards and Minnesota's supporting cast.
The Timberwolves also added Jonathan Kuminga, providing athleticism and another option on the wing.
But there are questions.
Ball's availability has been a recurring concern, and Minnesota must establish defensive consistency with its revised rotation.
Edwards and Ball also need to develop an effective partnership when both want to control the offense.
If the combination works, Minnesota could possess one of the Western Conference's most dangerous backcourts.
SportsIn60 projection: 53–29, Western Conference semifinalist.
Denver Nuggets: Jokic Gets Another Scoring Option
Nikola Jokic remains one of basketball's most dependable offensive forces.
Denver added DeMar DeRozan during the offseason, giving the Nuggets another experienced scorer alongside Jokic, Jamal Murray and Aaron Gordon.
DeRozan's ability to create shots in the half court could prove particularly useful when playoff opponents force Denver away from its preferred offensive actions.
The concern is defense.
Denver lost important supporting pieces, including Peyton Watson, and must determine whether its new rotation can defend athletic Western Conference opponents consistently.
Jokic virtually guarantees an efficient offense.
Whether Denver can produce enough defensive stops in a seven-game series will determine its championship ceiling.
SportsIn60 projection: 54–28, Western Conference semifinalist.
Lakers, Rockets and Portland: Three Different Paths
The Los Angeles Lakers enter a new era without LeBron James.
Luka Doncic now carries greater leadership responsibility, while the acquisition of Walker Kessler gives Los Angeles additional size and rim protection.
The Lakers have offensive talent, but their ability to defend consistently and build a reliable supporting cast around Doncic remains uncertain.
SportsIn60 projection: 47–35, playoff team.
Houston continues building around Kevin Durant, Amen Thompson and an athletic roster capable of challenging established contenders.
The Rockets have the defensive personnel to create problems for opponents, but late-game offensive execution and consistent outside shooting remain questions.
SportsIn60 projection: 50–32, playoff team with second-round potential.
Portland may be the Western Conference's most intriguing wild card.
The Trail Blazers acquired Ja Morant from Memphis, adding explosive speed and shot creation to a team that returned to the playoffs last season.
Morant joins a roster that also features Damian Lillard, creating fascinating possibilities in the backcourt.
The challenge is balancing playing time, offensive responsibilities and defensive effectiveness.
Morant's availability and ability to establish consistency will be essential.
SportsIn60 projection: 43–39, play-in contender.
Toronto's Kawhi Reunion and Milwaukee's New Direction
Kawhi Leonard's return to Toronto gives the Raptors a familiar championship figure.
Leonard helped deliver the franchise's first title in 2019, and his return provides veteran experience to a roster built around Scottie Barnes.
But Toronto surrendered Brandon Ingram, Gradey Dick and draft assets to complete the trade.
The Raptors need Leonard to remain healthy and productive to justify that investment.
SportsIn60 projection: 44–38, play-in contender.
Milwaukee faces a very different future following Antetokounmpo's departure.
The Bucks received Tyler Herro, Kel'el Ware, Jaime Jaquez Jr. and significant draft compensation in the Miami trade.
Those additions offer flexibility and younger talent, but replacing a two-time MVP is extraordinarily difficult.
Milwaukee's season will be more about establishing a new identity than immediately competing for a championship.
SportsIn60 projection: 30–52, outside the playoff field.
The Biggest Questions Entering the Season
Three issues could determine the championship race.
Health: Philadelphia needs Embiid and James available when the playoffs begin. Boston depends on Tatum's recovery, while Toronto and Minnesota have important availability concerns.
Chemistry: The 76ers, Heat and Timberwolves have acquired major stars, but integrating talent requires time. Teams that establish defined roles early could have an advantage.
Defense: The Western Conference features elite offensive players, but championship series often turn on which teams can execute defensively against multiple styles.
That last factor may be especially important.
San Antonio and Oklahoma City have the defensive personnel to challenge virtually any opponent without relying entirely on favorable matchups.
SportsIn60 Championship Prediction: Oklahoma City Thunder
San Antonio deserves its status as a leading contender. Wembanyama could become the league's most dominant two-way player, and the Spurs have already demonstrated their championship potential.
Philadelphia may have the most impressive collection of established stars, while New York has the experience of winning the title.
But our selection is Oklahoma City.
The Thunder combine an established superstar in Gilgeous-Alexander with a versatile supporting core, proven coaching and a defensive identity that can survive difficult shooting nights.
Their offseason departures create legitimate concerns, particularly against the Spurs' size and Minnesota's athleticism.
Still, Oklahoma City's continuity gives it an advantage over teams trying to incorporate multiple new stars.
The Thunder also have the offensive versatility to attack different defensive schemes, with Gilgeous-Alexander creating pressure at the rim and Holmgren providing spacing and interior defense.
Our projected Finals matchup is Oklahoma City versus New York.
The Knicks' experience, Brunson's late-game scoring and defensive toughness should make the series competitive.
But Oklahoma City's combination of perimeter creation, length and defensive adaptability gives it a narrow advantage.
SportsIn60 prediction: Oklahoma City defeats New York in six games to win the 2027 NBA championship.
The offseason belonged to Philadelphia and Miami.
The preseason attention belongs to San Antonio.
But when the championship is decided in June, Oklahoma City is our pick to finish on top.
