BOSTON — The brooms were never actually in play. But the champagne? The rest? The easy path to the Eastern Conference semifinals? All of it was right there, sitting on the edge of the TD Garden parquet, waiting for the Celtics to simply reach out and grab it.
One win. That’s all they needed. One more quarter of good basketball. One more burst of the energy that had carried them to a 13-point lead early in the second half. One more reminder that they were the better team in this series.
Instead, the Celtics delivered one of the ugliest, most inexplicable collapses in recent playoff memory.
The final score: Philadelphia 113, Boston 97. A 16-point loss on their home floor. A blown 13-point lead. A fourth quarter so offensively wretched that it felt like a fever dream — 3-for-22 from the field, 11 points, outscored 28-11 by a Sixers team that was supposed to be booking summer vacation plans.
“We just missed some shots,” head coach Joe Mazzulla said afterward, in what has to be the understatement of the postseason.
Missed some shots? The Celtics shot 11-for-39 from three-point range (28.2 percent). They shot 3-for-22 in the fourth quarter. They went the final seven minutes of regulation without a single made field goal. Seven minutes. In an elimination game at home. Against a team that had lost three straight and was playing without its home crowd.
Jayson Tatum and Jaylen Brown, the two All-NBA wings who are supposed to carry this team through moments like this, combined for just two points in the fourth quarter. Two. Tatum finished with 24 points on 8-of-19 shooting, plus 16 rebounds — a solid line on paper, but hollow when it mattered most. Brown had 22 on 9-of-23, but disappeared when the game tightened.
Derrick White, who has been the Celtics’ playoff rock for years, continued his series-long shooting slump: 0-for-4 from three, invisible on a night when Boston needed every available hand on deck.
The series is not over. The Celtics still lead 3-2. They still have two chances to close out the Sixers. But after Tuesday night’s disaster, the momentum has shifted. The confidence has cracked. And the Celtics are heading to Philadelphia for a Game 6 that suddenly feels like a Game 7.
Let’s break down what went wrong, why the Celtics’ offense vanished, and whether Boston can regroup before it’s too late.
The Fourth Quarter From Hell — 3-for-22, 11 Points, 28-11 Run
Let’s start with the numbers that matter most.
In the fourth quarter of Game 5, the Boston Celtics shot 3-for-22 from the field.
Read that again. Three made field goals. Twenty-two attempts. The Celtics missed 19 of their 22 shots in the final 12 minutes of a game that would have sent them to the second round. They scored 11 points. The Sixers scored 28. The game went from tight to over in a matter of minutes.
Joe Mazzulla’s explanation was characteristically understated:
“We just missed some shots. I thought we got some good looks, and we didn’t really capitalize on them.”
But “missed some shots” doesn’t capture the horror of what actually happened. The Celtics didn’t just miss — they imploded. They rushed possessions. They settled for contested threes. They stopped moving the ball. They stopped trusting the offense that had worked so well in Games 1 through 4.
And the Sixers? They capitalized. Every missed shot became a transition opportunity. Every defensive rebound turned into a quick outlet to Tyrese Maxey or Quentin Grimes. The lead swelled. The crowd deflated. The Celtics’ body language screamed defeat long before the final buzzer.
The Stars Went Dark — Tatum and Brown Ghost in the Fourth
Let’s talk about the two players who are supposed to prevent exactly this kind of collapse.
Jayson Tatum and Jaylen Brown are All-NBA players. They’ve been to the Finals. They’ve won championships. They’ve hit big shots in big moments. They are not supposed to combine for two points in a fourth quarter when their team is trying to close out a first-round series.
But that’s exactly what happened.
Tatum finished with 24 points, 16 rebounds, and a solid shooting line (8-of-19). On paper, that’s a productive night. But paper doesn’t capture the fourth quarter, when Tatum went quiet, settled for difficult jumpers, and failed to impose his will on a game that was begging for a superstar to take over.
Brown had 22 points on 9-of-23 shooting, but his impact faded as the game wore on. He committed early turnovers. He struggled to find rhythm. And when the Celtics needed someone — anyone — to stop the bleeding, Brown couldn’t answer the call.
This is not meant to pile on. Tatum and Brown have carried the Celtics all season. They’ve earned the benefit of the doubt. But in Game 5, they were not good enough. And in the NBA playoffs, good enough is the difference between advancing and going home.
The White Struggle — A Series-Long Slump Reaches Its Nadir
Derrick White has been one of the most reliable playoff performers in the NBA over the past several years. He hits big shots. He makes winning plays. He is the kind of player who elevates his game when the lights are brightest.
That has not been the case in this series.
White’s shooting struggles continued in Game 5: 0-for-4 from three-point range, a quiet presence on a night when the Celtics needed his floor spacing and his defensive versatility. He finished with just four points in 30 minutes — a ghostly performance from a player who is usually anything but.
The Celtics can survive one cold-shooting night from White. They did in Game 4, when Payton Pritchard exploded for 32 points off the bench. But they cannot survive a series-long slump from their starting guard. At some point, White has to find his rhythm. The Celtics need him. Game 6 is Thursday. The clock is ticking.
The Queta Foul Trouble — A Promising Start Derailed
Let’s give credit where it’s due: Neemias Queta had a strong first quarter. He grabbed eight rebounds. He played with energy. He looked like a legitimate playoff contributor.
Then the fouls started.
Queta picked up his fourth foul midway through the third quarter, forcing Mazzulla to send him to the bench. With Queta out, the Celtics’ defense lost its rim protector. The Sixers attacked the paint. They got to the free-throw line. They opened up the perimeter for the barrage of threes that would eventually bury Boston.
Queta’s foul trouble wasn’t the only reason the Celtics lost. But it was a contributing factor — a reminder that depth matters in the playoffs, and that Boston’s frontcourt is thinner than it looks.
The Sixers’ Resilience — Embiid, Maxey, and Grimes Refuse to Quit
Let’s not pretend the Celtics lost in a vacuum. The Philadelphia 76ers played well. They deserved to win.
Joel Embiid, in his second game back from an appendectomy, looked like the MVP candidate he is: 33 points, 8 assists, a dominant presence on both ends of the floor. He was aggressive. He was engaged. He refused to let his team’s season end.
Tyrese Maxey added 25 points and 10 rebounds, playing with the kind of relentless energy that has defined his young career. He pushed the pace. He attacked mismatches. He made the Celtics pay for every defensive lapse.
And Quentin Grimes was the X-factor off the bench: 18 points on 5-of-8 shooting, four threes, and a three-shot foul that deflated the Garden crowd. Grimes has been a revelation for the Sixers in this series — a role player who has stepped up when his team needed him most.
The Sixers didn’t just beat the Celtics. They out-executed them. They out-hustled them. And they refused to go away, even when trailing by 13 points early in the third quarter.
That’s championship DNA. That’s the kind of resilience that wins playoff series. And right now, the Sixers have it, and the Celtics don’t.
The Pritchard Problem — From Hero to Zero
Payton Pritchard was the hero of Game 4. He scored 32 points off the bench. He hit six threes. He looked like the best sixth man in the league.
In Game 5, he had three points in the second half. Zero assists. He was a non-factor when the Celtics needed him most.
Pritchard’s second-half disappearance is a microcosm of the Celtics’ larger issue: inconsistency. They have been brilliant in some games (Games 1, 3, and 4) and dreadful in others (Games 2 and 5). They have yet to put together a complete, four-quarter performance in this series.
That inconsistency will get them bounced in the second round — or sooner — if they don’t fix it.
Part 7: The Road Ahead — Game 6 in Philly, Everything on the Line
The series now shifts to Philadelphia for Game 6 on Thursday night. The Celtics still lead 3-2. They still have two chances to close out the Sixers. But the momentum is no longer on their side.
Philadelphia has all the confidence. They just won a road game against a top seed. They have Embiid looking healthy and dominant. They have Maxey playing like a star. They have role players who are stepping up.
The Celtics, meanwhile, have questions. Can Tatum and Brown respond after a fourth-quarter no-show? Can White snap out of his shooting funk? Can Mazzulla adjust his rotations? Can anyone on this team hit a shot when it matters most?
These are not small questions. These are existential questions for a franchise that has championship aspirations.
The good news for Boston: they’ve been here before. They’ve faced adversity. They’ve responded. Tatum and Brown have a history of bouncing back from bad games.
But the bad news: Philadelphia is not going to roll over. They believe they can win this series. And after Game 5, they have every reason to believe.
The Celtics blew a chance to end things on their home floor. They let a 13-point lead slip away. They went seven minutes without a field goal when it mattered most. They have no one to blame but themselves.
Now they have to go on the road and prove they’re still the better team.
Game 6 is Thursday. The season is on the line. The Celtics have two days to figure it out.
If they don’t? Then Tuesday night’s collapse won’t just be an ugly memory. It will be the start of an offseason full of questions.
The Celtics had the Sixers on the ropes. They were up 3-1. They were playing at home. They had a 13-point lead. And then they stopped playing.
The fourth quarter was a disaster. Three-for-22 from the field. Eleven points. A 28-11 run by Philadelphia. Jayson Tatum and Jaylen Brown combined for two points in the final 12 minutes. Derrick White went 0-for-4 from three. Payton Pritchard vanished.
“We got a little lackadaisical when we could have put them away,” Pritchard admitted.
Lackadaisical. That’s the word. The Celtics got comfortable. They got careless. They forgot that playoff series don’t end until the fourth win is secured.
Now the series shifts to Philadelphia. The Sixers have life. The Celtics have questions.
Can they regroup? Can they close this out on the road? Or will Tuesday night’s collapse be remembered as the moment a championship contender lost its nerve?
We’ll find out Thursday. Game 6. Philly. Everything on the line.
The Celtics blew their chance to end this early. Now they have to earn it the hard way.
