Every NBA offseason has one move that everybody talks about and a different move that actually changes the league. This summer the loudest name was Giannis. The second loudest was LeBron. Neither one is the answer.
The most important thing that happened this offseason was Jaylen Brown getting traded to Philadelphia. And the reason why starts in Milwaukee.
Here's the chain. Boston went hard after Giannis in June and offered Brown and two first-round picks. Milwaukee took Miami's package instead, and the same day the details of Boston's offer went public. That's now twice in four years the Celtics had shopped Brown for another star, the first time being Kevin Durant in 2022. On July 1 they traded their 2024 Finals MVP to the Sixers for Paul George, two firsts and two seconds. Brown said afterward he was still processing how it all went down. Then, with Brown, Embiid, Maxey and VJ Edgecombe on the roster, Philadelphia became the place LeBron James picked for his last run. The reporting on why was blunt. The Sixers' stacked roster gave him the best shot at a title with a fourth franchise.
One failed trade created two of the biggest moves of the summer. Rank them by what they actually change in May, and the order looks different than the headlines.
Just missing the list are the two point guards who changed zip codes. LaMelo Ball went to Minnesota, along with Josh Green, for Naz Reid, an unprotected 2033 first, three pick swaps and three seconds. Ja Morant went to Portland for Jerami Grant and Kris Murray. Both are interesting. Neither moves a title race.
Fourth is LeBron. He signed for two years and $8 million, chasing what would be the first title ever won with a fourth franchise. He's also 41, he averaged 20.9 points in 60 games last season, and in Philadelphia he's the third or fourth option on a good night. He raises the Sixers' floor and their national TV count. He doesn't decide whether they win a title. Embiid's health decides that. LeBron is the biggest name to move and the smallest basketball change on this list.
Third is Kawhi Leonard to Toronto, for Brandon Ingram, Gradey Dick, two firsts, two seconds and a pick swap. People forgot how good Kawhi was last season. He played 65 games and averaged a career-high 27.9 points with 1.9 steals at 34 years old, on a Clippers team that finished 42-40. Put that player next to Scottie Barnes and a Raptors team that won 46 games and you have a real problem for the top of the East.
The catch is the same catch it always is. From 2021 through 2025, the Clippers played 37 playoff games. Kawhi played in 22 of them. Kawhi is the highest variance move of the summer. If he's healthy in April, Toronto is a conference finals team and this trade belongs at the top of the list. If he isn't, Toronto traded a healthy Ingram and two firsts for a very expensive spectator. You can't rank a move first when the most likely outcome is a coin flip.
Second is Giannis to Miami, and I know that sounds wrong. He's the best player who moved. A two-time MVP, 27.6 points and 9.8 rebounds a game last season, and the reason Milwaukee has a banner from 2021. Talent alone, he's number one and it isn't close.
But impact isn't talent. It's what changes. Look at what Miami gave up: Tyler Herro, Jaime Jaquez Jr., Kel'el Ware, Kasparas Jakucionis, this year's 13th pick, two more firsts and a pick swap. That was most of the depth on a team that went 43-39 and lost in the play-in. What's left is Giannis and Bam Adebayo up front, neither of whom is a reliable outside shooter, with Davion Mitchell, Klay Thompson and Andrew Wiggins around them. And Giannis played a career-low 36 games last year before a knee injury ended his season.
So the Heat got a lot better and probably still aren't better than the Knicks or the Sixers. The bigger change might be in Milwaukee, which missed the playoffs last year for the first time since 2016 and has now officially started over. That's a real shift. It's just not a shift at the top.
Which brings it back to Brown.
Before July, the East had one clear favorite. The Knicks won the title, swept the Sixers in the second round on the way, and brought back Brunson, Towns, Hart, Bridges and Anunoby. Philadelphia was a talented team that hadn't gotten out of the second round since 2001. Boston was still Boston.
Brown changed all three of those sentences at once. He turned Philadelphia from a team built around Embiid's health into a team with a two-way wing who has already won a Finals MVP. He cleared out the roughly $110 million left on George's deal. He's the reason Philly was the roster LeBron picked. And he pulled Boston's second-best player out of a conference rival and dropped him into a different one. As of this week, sportsbooks have Philadelphia tied with the Knicks for the best championship odds of any team in the East.
And here's what gets lost. Brown is 29. Giannis is 31, Kawhi is 35, LeBron is 41. Of the four biggest names who moved this summer, Brown is the only one whose best seasons could still be in front of him with his new team. The others are buying a window. Philadelphia bought a player.
That's the definition of impact. Not who's the best player, but whose move rearranges the most teams. Brown's trade reshaped Boston, made Philly a co-favorite and recruited the most famous player in the sport without Brown saying a word. All of it traces back to a Giannis trade that didn't happen in Boston.
