After an offseason of massive free agent signings, blockbuster trades and the captivating Olympic Games in Paris, the 2024-25 NBA season will tip off on Tuesday.

While player movement and new rosters have grabbed the majority of the headlines since June, the defending champion Boston Celtics remain mostly unchanged and poised to make a run at a repeat.

Jayson Tatum returns as one of the top scorers in the league, and Jaylen Brown is coming off a Finals MVP performance. Tatum, however, barely played for this year’s gold medal-winning Team USA squad – and Brown was left off the roster entirely – despite Boston teammates Derrick White and Jrue Holiday playing key roles in Paris.

These dynamics could cause a lesser team to engage in a power struggle, but the core of this Celtics team appears to be as cohesive as they come, with Brown and Tatum gladly passing the “primary scorer” baton back and forth in their seven seasons together.

The Celtics finished last season 64-18, then followed with a 16-3 post-season, making them one of the most dominant champions in recent memory. Sports books have forecasted Boston’s win total this season at 58.5, the highest in the league.

With Tatum and Brown still in the heart of their primes, the Celtics will be difficult to dethrone, but Al Horford, 38, and Holiday, 34, may begin to regress. Boston will also closely monitor the status of Kristaps Porziņģis, who underwent left leg surgery in June and may be out until the calendar turns to 2025.

Knicks, Sixers load up to compete in East

The Celtics’ most likely challengers in the Eastern Conference appear to be the New York Knicks and the Philadelphia 76ers, both of whom made attention-grabbing acquisitions in the offseason.

The Knicks lost Isaiah Hartenstein to free agency but made a massive trade to acquire Karl-Anthony Towns. The multi-talented big man joins a stacked starting lineup that includes Jalen Brunson, Mikal Bridges and OG Anunoby.

New York won 50 games last season before injuries decimated their play-off hopes. This year’s squad is undoubtedly more talented than last year’s, but how quickly can this group gain cohesion after losing three of last season’s top five scorers?

The Knicks will play in the NBA’s tip-off game Tuesday in Boston, where the Celtics will raise another championship banner.

The 76ers were successful in their gambit to accrue salary cap space for last offseason and made a massive addition in signing Paul George to a four-year max contract that includes a player option.

George teams up with former MVP Joel Embiid and rising star Tyrese Maxey on a team with title aspirations. Philadelphia also added veteran role players this offseason in Andre Drummond, Eric Gordon, Caleb Martin and Reggie Jackson.

The 76ers are built to contend this season but face a number of durability questions. Embiid announced last week that he will not play on back-to-back nights after missing 45 games last season. George, 34, played 74 games last season but averaged 47 games played over the previous four seasons.

Philadelphia have said that their sole focus will be on having a healthy roster when the playoffs start in April, so Embiid and George could have plenty of rest days during the regular season. 

While Philly and New York appear to be Boston’s most formidable challengers in the East, others are lurking just a tier below.

The Milwaukee Bucks expect the second year of the Giannis Antetokounmpo-Damian Lillard pairing to yield better results under coach Doc Rivers, while Tyrese Haliburton and a young Indiana Pacers team will look to build on last season’s Eastern Conference finals appearance.

James family history

While the Western Conference is loaded with championship contenders, a team likely outside the title conversation has stolen most of the attention this offseason.

The Los Angeles Lakers used the 55th overall pick in June’s draft on Bronny James, making him teammates with his father, LeBron James. The pair will become the first father-son duo to play in the same NBA game.

Bronny struggled in six preseason games, shooting under 30 percent from the field and racking up more turnovers than assists. Even if Bronny spends most of the season in the G League, the Lakers will almost certainly allow him to take the court with his legendary father at some point.

The elder James will celebrate his 40th birthday this season as the future Hall of Famer enters his 22nd NBA season.

While James seems to have defied the aging process over the last several years, Los Angeles will likely ease his workload and give more opportunities to Anthony Davis, Austin Reaves and DeAngelo Russell.

James and Davis missed just 17 combined games last season, and the Lakers will need a similarly healthy season to compete in a loaded West.

MVP race: West is best

Luka Dončić won last season’s scoring title at 33.9 points per game and guided the Dallas Mavericks to an NBA Finals appearance.

The Mavs added veteran sharpshooter and long-time Golden State Warrior Klay Thompson in hopes of a title run and will be banking on big growth from second-year center Derek Lively II.

Dončić opens the season as the betting favourite to win MVP, but he will have plenty of competition both for personal accolades and team success.

Nikola Jokić was voted MVP for the third time last season and enters the 2024-25 season as one of the favourites, although he would need a truly spectacular season to overcome voter fatigue and win a fourth MVP in a five-year span.

After the free agent departures of Kentavious Caldwell-Pope, Bruce Brown and Jeff Green the last two off-seasons, the Nuggets will need contributions from younger players and will hope Jamal Murray’s health improves as the season progresses.

For years, the Oklahoma City Thunder were considered a sleeping giant, and OKC has signalled over the past year that they are ready for contention.

The Thunder were the top seed in the West last season with a 57-25 record, then used the playoffs to identify weaknesses and gain experience. OKC acquired Alex Caruso and Isaiah Hartenstein in the offseason, giving them a better-fitting and more flexible roster, and the Thunder enter this season as the favourites in the West.

Hartenstein will miss the first six-or-so weeks of the season after breaking his left (shooting) hand, but once healthy he should help negate a rebounding weakness that doomed the Thunder in the playoffs.

Shai Gilgeous-Alexander is among the MVP favourites after averaging 30.1 points, 5.5 rebounds and 6.2 assists last season while shooting a career-high 53.5 percent from the field.

As deep and talented as the Thunder are as currently constructed, they own a staggering amount of future draft capital and could become a juggernaut if they decided to trade for another star player.

The Minnesota Timberwolves turned heads with their run to the West finals last season and stunned the basketball world when they traded Karl-Anthony Towns for Julius Randle and Donte DiVincenzo.

The decision to move on from Towns puts more of the offensive load on Anthony Edwards, whose scoring and efficiency have improved each year since being the No. 1 overall pick in 2020.

Minnesota made easy work of the Phoenix Suns last post-season, but the Suns will look to rejoin the contenders’ conversation as Kevin Durant, Devin Booker and Bradley Beal enter their second season as a teammate trio.

Wembanyama: A matter of time

One of the most prevalent storylines entering 2024-25 is the continued growth of Victor Wembanyama in his second NBA season.

Wembanyama had one of the best rookie seasons in recent memory, with the 7-foot-4 center leading the league in blocks and finishing second in Defensive Player of the Year voting.

Wembanyama followed with an impressive run in the Paris Olympics and has hit all the early checkpoints of a future MVP.

Most experts agree that the San Antonio Spurs aren’t ready to compete for a play-off spot this season, but Wembanyama seems destined to become a top-five player, and his ascendancy could happen sooner rather than later.

Flounder for Flagg?

This year’s rookie class is full of questions, but prognosticators are bullish on several top prospects in the 2025 class, setting the stage for a race for the bottom.

Duke forward Cooper Flagg is projected to be a two-way force and is the consensus No. 1 prospect in the class after playing with Team USA Select Team over the summer.

Baylor’s VJ Edgecombe, along with Ace Bailey and Dylan Harper of Rutgers, have also got scouts excited in a draft class considered much deeper than 2024’s crop.

With one or more possible franchise-changers available in the 2025 draft, many of the NBA’s less talented teams will be content to sit at the bottom of the standings this season, especially in the Eastern Conference.

From the Washington Wizards to the Brooklyn Nets to the Portland Trail Blazers, there will be a handful of organisations focused more on the 2025 draft than their 2024-25 record.
