The 15

It’s been a rough few months for the Celtics, to say the least. It’s not often that people look at a roster featuring a four-time All-NBA First Team superstar, a Finals MVP, a reigning Coach of the Year, and a two-time Executive of the Year — and still feel the team has hit a wall. In some ways, the Celtics have. If there is a fault in Joe Mazzulla’s philosophy, it isn’t shooting too many threes. It’s the lack of an off-switch from their frantic style in the playoffs, when defenses can game-plan around Boston’s desire to win the numbers battle. It’s hard to make your threes when you can’t attack the basket against drop coverage. The Celtics have failed to generate good looks in the clutch during the playoffs in two straight years, and it has resulted in early exits that have dramatically shaken the confidence this group built from their title run.

Getting Giannis was supposed to fix that. But for whatever reason, the pursuit fell through. We can blame Brad Stevens for not going all-in, refusing to include Hugo Gonzalez, Baylor Scheierman, and more picks on top of the two first-rounders the Celtics are confirmed to have offered. Or we can believe the rumor that Bucks owner Jimmy Haslam nudged GM Jon Horst toward accepting Miami’s offer out of fear that Jaylen Brown would demand a trade.

Sources say Bucks owner Jimmy Haslam was a driving force in taking the Heat deal for Giannis over Boston’s offer. Haslam didn’t want to risk Jaylen Brown wanting out of Milwaukee in a year after dealing with Giannis and Myles Garrett trade demands. Haslam wanted certainty, and…

No matter who we blame, the Miami Heat now have Giannis Antetokounmpo, and the Celtics do not. Their problems remain the same as before, and the clearest avenue to address them is closed. It’s easy to fall into despair and remember the later days of the Big Three era, when it felt like Danny Ainge couldn’t make the necessary moves to prop up an aging core while rivals got younger, faster, and better.

The silver lining is that Stevens isn’t wrong, in a vacuum, to walk away if he believed the price was too high. We’ll see how Miami builds around Bam Adebayo and Giannis. They are undeniably thin in an era where the last three NBA champions have been incredibly deep. They do still hold their 2028 and 2029 first-round picks, and we’re about to find out how valuable those picks are now that Miami won’t be lingering in the play-in. If the Heat can navigate these limitations and win a title or two, Stevens getting cold feet will look worse. If they fail, the bill will come due, the Heat will be in hell, and the Celtics will still have options.

The three most gnawing words fans hate to hear: wait and see.

The advice I’ll give Celtics fans is this: stay off Twitter. Stay off Reddit. If news breaks, you’ll find out the way your fathers and grandfathers did — a friend will tell you. If it’s any consolation, Jaylen appears ready to let bygones be bygones. Unless Stevens pokes the bear and tries to trade the two-time All-NBAer a second time in one summer and that deal also falls through, it’s safe to assume Brown will remain a Celtic for the foreseeable future. The front office will pivot to addressing their pitiful situation at center and may look into trading Derrick White.

For all the faults I’ve previously laid out about “Mazzulla-Ball,” it is uniquely suited to churning out 50-win seasons and making us forget the various weaknesses this team possesses. After all, we entered the past playoffs thinking we were a Finals team with Neemias Queta, Luka Garza, and Nikola Vučević as our centers. We’ll see if White can rediscover his jump shot. If a fully healthy Jayson Tatum will fix Boston’s problem of going 3-11 against the NBA’s best teams last season. If another year of Jordan Walsh as a lockdown bench defender — along with Hugo and Baylor as reserve spark plugs — can move the needle.

Can they beat New York, Miami, Detroit, or Philadelphia as currently constructed? Probably not. And that feeling truly sucks. But there’s no use dwelling on it now. Situations change. Things can shift in a month or two. Even if everything remains the same and the Celtics fail at every plan to improve this offseason, they’ll have plenty of flexibility next summer — perhaps making it easier to trade Brown and/or White under new circumstances.

We. Will. See.
