The Boston Celtics are the front-runners to land Giannis Antetokounmpo, but the trade would force them to confront a financial and roster challenge: how to accommodate a four-year, $275 million extension while maintaining their championship-winning core. According to NBC Sports Boston, the deal would likely require trading Jaylen Brown, who is set to make $57 million next season, and navigating the NBA’s new collective bargaining agreement, which makes sustaining two $60-million-plus superstars unsustainable.
Why Boston’s Financial Math Doesn’t Add Up
Antetokounmpo’s $275 million extension—eligible six months after a trade—would pair with Jayson Tatum’s $58 million salary next season, creating a payroll crunch. “Look, the fact is it’s hard to win with two players making $60-plus million,” Yahoo Sports’ Kevin O’Connor said on Early Edition. The Celtics have already seen this formula fail: the Knicks won the title in 2023 with a rotation that often played one superstar at a time, while Oklahoma City and Indiana’s deep rosters in 2025 relied on balanced spending. The new CBA’s luxury tax thresholds make Boston’s current approach—two stars at $60M+—a high-risk gambit.

Adding to the complexity, Antetokounmpo’s $63 million player option for 2026-27 would push his total to $338 million over five years, a figure that would require Boston to either shed salary or restructure contracts. The Celtics’ current cap space is tight, with Brown ($57M), Tatum ($58M), and Marcus Smart ($25M) already locking up $140 million annually. “It can’t be just Giannis,” O’Connor warned. “There would have to be more moves to follow.”
The Celtics’ Roster Problem: Can Mazzulla-Ball Work?
The second misconception about Antetokounmpo in Boston is that his arrival would force a radical shift in offensive strategy. SI.com debunks this idea, pointing out that the Bucks—under both Mike Budenholzer and Doc Rivers—have consistently ranked in the top five in three-point attempts since 2018, even with Antetokounmpo as a non-shooter. His drives create open lanes for shooters, and he’s assisted on more three-pointers (2,325 career) than Brown and Derrick White have made combined (2,437).

Yet Boston’s offense thrives on spacing, and Antetokounmpo’s career 28.5% three-point shooting—peaking at 34.7% in his rookie year—raises questions. “Mazzulla-ball” relies on shooters like Brown (196 three-pointers created last season) and Tatum, but adding Antetokounmpo could clog drives. The Bucks’ solution was Brook Lopez at center, but Boston’s closest stretch-four, Nikola Vucevic, never found his footing. Without a true rim protector or a secondary scorer who can space the floor, the Celtics’ offense might struggle to adapt.
Miami’s Edge: Why the Heat Are Still the Favorites
While Boston and the Celtics remain in the conversation, the Miami Heat have maintained their lead in the Giannis sweepstakes. According to The New York Times, Miami’s package—Tyler Herro, Kel’el Ware, Jaime Jaquez Jr., and up to three first-round picks—remains the most competitive. The Heat’s willingness to include draft capital (including picks as late as 2033) gives them flexibility, while Boston would need to navigate a three-team deal to land Antetokounmpo without overpaying for Brown.

Antetokounmpo’s interest in Miami is well-documented, but the Bucks’ front office is testing the market. “The Bucks are seeking clarity from several suitors,” The Times reports, including the Celtics, Timberwolves, and Magic. However, Miami’s roster—with Herro as a proven shooter and young talent like Jaquez—aligns better with Antetokounmpo’s need for a winner. The Heat’s championship pedigree and Pat Riley’s track record also give them an edge in convincing Giannis to commit.
What Happens Next: The Celtics’ Plan B
If Boston misses out on Antetokounmpo, the Celtics may still need to move Jaylen Brown. O’Connor suggested Brad Stevens has “Plan B or C” to flip Brown elsewhere for assets. The New Orleans Pelicans’ package—Trey Murphy, Herb Jones, and draft capital—has been floated as a potential fit, though it would require Boston to rebuild around Tatum and a younger core. “I can’t imagine Brown would be too happy going back to Boston if they don’t land Giannis,” O’Connor said, hinting at a potential trade deadline move.
The bigger question is whether Boston’s front office is willing to gamble on Antetokounmpo’s fit. The financial math is daunting, the roster adjustments are unproven, and the Heat’s offer remains the most enticing. Yet if the Celtics believe they can build around Giannis—while shedding Brown’s salary—they may still pursue a three-team deal. The window to act is narrow: the Bucks have set a self-imposed deadline before the June 23 draft, and Antetokounmpo’s agent will push for a resolution soon.
The Bigger Picture: What a Giannis Trade Means for the NBA
A trade for Antetokounmpo would mark the end of an era for the Bucks, who have been the league’s most consistent winner since 2019. His departure would force Milwaukee to rebuild, potentially accelerating their draft strategy. For Boston, the move would either redefine their championship window or accelerate their decline if the financial and roster adjustments fail. Meanwhile, the Heat’s success in landing Giannis would solidify their status as title contenders, while other suitors—like the Timberwolves or Pacers—would need to step up their offers to remain in the conversation.

The NBA’s new CBA complicates these deals, as teams now face stricter salary-cap constraints. The Knicks’ 2023 title win—with a rotation that often played one superstar at a time—suggests the league may be shifting toward a “one big star plus depth” model. If Boston proceeds with Antetokounmpo, they’ll need to prove they can adapt without sacrificing their offensive identity. For now, the Heat remain the most likely destination—but the Celtics’ pursuit underscores how high the stakes are for both teams.
One thing is certain: the Giannis trade saga won’t end with a simple swap. It will require creative deals, financial acrobatics, and a willingness to reshape rosters. The question is whether Boston—or any team—can pull it off without breaking the bank.
