The Boston Celtics appear to be barreling toward their 19th NBA championship and 15th 60-win season in the teamâs history. The Celtics hold the record in both categories and with 56 wins and six games left, the latter appears a near-certainty.
As winners of 14 of their last 16 games and 20 of their last 24, the Celtics are taking considerable momentum into the playoffs, where FanDuel currently gives them odds of +185 to win the championship â second only to the Oklahoma City Thunder (+170).
But how long can the Celticsâ dominance last? With a player payroll just shy of $200 million, Boston is almost $4.5 million over the salary capâs âsecond apron,â a threshold that comes with severe financial penalties and tight restrictions on trades and other types of player movement, making it extremely difficult for second apron teams to improve, or sustain success.
ESPN Names Tatum Best NBA Comp For Flagg

If the Celtics can replace one high-paid player with another making less money but of comparable abilities, they could find a solution to their second-apron problem. That player could be Cooper Flagg, the Duke star and consensus No. 1 pick in the upcoming NBA draft. According to an ESPN analysis based on interviews with NBA front office executives and scouts, the NBA player in his prime most comparable to Flagg is Celtics superstar Jayson Tatum.
Entering next season, the Celtics are looking at exceeding the second apron by $18 million. Using calculations by ESPNâs Tim Bontemps, that would put the Celtics total player expenditures including the financial penalties for exceeding the second apron line at more than $500 million.
Celtics outgoing owner Wyc Grousbeck, who authorized team president of basketball operations Brad Stevens to cross the second apron line in assembling the powerhouse team that cruised to the 2023-2024 NBA championship, said in a recent interview with Boston radio station WEEI, âBecause you have to navigate because you canât stay in the second apron, nobody will, I predict, for the next 40 years of the CBA, no one is going to stay in the second apron more than two years.â
Now the Celtics have a new owner â private equity financier and Massachusetts native, and self-proclaimed lifelong Celtics fan William âBillâ Chisolm.
After leading an investment group that bought the team in a sale announced March 20 for a record $6.1 billion, Chisolm declared âI want to raise banners. I want to raise them now, and I want to raise them in the future as well.â
âBilly Bannersâ Faces Need to Trim Celtics Payroll

That may have earned him the nickname âBilly Bannersâ among Celtics fans, but how realistic is it, given Grousbeckâs prediction that no team can stay in the second apron for more than a couple of years? Chisolm will likely have no choice but to trim payroll â and the quickest way to do that would be to deal away the Celticsâ highest-paid player, Jayson Tatum.
Last offseason, Tatum qualified to sign a type of contract known under the NBA Collective Bargaining Agreement as a Designated Veteran Player Extension, better known as a âSuperMax.â The details are complex, but the bottom line is that starting in the 2025-2026 season, Tatumâs salary jumps by nearly $20 million, to $54.1 million. Tatumâs pay then goes up each year until the final year of his SuperMax deal, when if he exercised his player option, Tatum would collect an astounding $71.45 million for a single season of basketball.
According to a plan laid out by Ringer founder Bill Simmons, the Celtics could make a move to acquire Flagg once his four-year rookie contract is up. At that point, Flagg would not be eligible for a SuperMax contract, meaning he would cost considerably less than Tatum. But is he really a replacement for the future Hall of Famer, who also played his âone and doneâ year of college ball at Duke?
Jazz, Hornets, Wizards Favored to Draft Flagg
âTatumâs balanced, high-volume offensive profile with the Celtics shows how Flagg could grow into a similar role â particularly if his future team guides him toward high usage,â wrote ESPN analyst Jeremy Woo. âFlagg is a more accomplished playmaker for others, more than doubling Tatumâs assists per game at Duke, and the passing figures to be more central to his offensive value in the NBA. Flaggâs shot selection is a bit more team-friendly, but while he has made strides creating his own shot in the half court, Tatum was more polished.â
Of course, whether the Celtics can acquire Flagg before Tatumâs SuperMax contract expires is to some degree up to the team that drafts him. According to FanDuel odds, the Utah Jazz, Washington Wizards and Charlotte Hornets are tri-favorites at +500 to land Flagg with the No. 1 pick coming out of the NBA draft lottery.
The New Orleans Pelicans, Philadelphia 76ers and Brooklyn Nets also have decent FanDuel odds to land Flagg, at +600, +700 and +850, respectively.
