Celtics Dominate 76ers in Game 1 as Tatum, Brown Lead Playoff Surge

BOSTON — Jayson Tatum and Jaylen Brown delivered a statement performance as the Boston Celtics overwhelmed the Philadelphia 76ers 123-91 in Game 1 of their Eastern Conference first-round playoff series, setting the tone with a 32-point victory that underscored Boston’s offensive firepower and defensive discipline.

The Celtics, entering the playoffs as the Eastern Conference’s top seed with a 64-18 regular-season record, executed a near-flawless game plan from tip-off. Tatum finished with 30 points, eight rebounds, and five assists, although Brown added 26 points, seven rebounds, and four assists. Their combined 56 points accounted for nearly half of Boston’s total output, and both shot efficiently — Tatum at 11-for-19 from the field and 4-for-7 from three, Brown at 9-for-16 and 3-for-5 from beyond the arc.

“We came in with a clear mindset: impose our will early and make them uncomfortable,” Tatum said after the game. “Jaylen and I have been through enough battles together to know when it’s time to take over. Tonight was one of those nights.”

The victory marked the Celtics’ largest margin of victory in a playoff game since 2008 and their biggest win in a postseason opener since defeating the Chicago Bulls by 31 points in 1986. Philadelphia, which finished second in the Atlantic Division with a 52-30 record, struggled to find rhythm offensively, shooting just 38.1% from the field and 28.6% from three-point range.

Defensive Anchor: Holiday and White Stifle Sixers’ Backcourt

While Tatum and Brown garnered the headlines, Boston’s defensive effort was equally instrumental. Jrue Holiday and Derrick White combined to hold Sixers’ star Tyrese Maxey to 12 points on 4-for-15 shooting, forcing him into six turnovers. Holiday, a former Defensive Player of the Year candidate, recorded three steals and consistently disrupted Philadelphia’s pick-and-roll actions.

“Holiday’s ability to switch onto Maxey and stay attached made a huge difference,” said Celtics head coach Joe Mazzulla in his postgame press conference. “He didn’t just defend — he initiated. That pressure forced Philadelphia into tough shots and live-ball turnovers, which we turned into transition points.”

The Celtics forced 18 Sixers turnovers, converting them into 24 points. Boston outscored Philadelphia 28-8 in fast-break opportunities and held a 22-6 advantage in points off turnovers — a stark illustration of how Boston’s defensive intensity translated directly into offensive momentum.

Sixers Struggle Without Embiid’s Full Impact

Joel Embiid, playing through lingering discomfort in his left knee, finished with 18 points and nine rebounds but shot just 6-for-19 from the field. The Sixers’ star center, who averaged 34.7 points per game during the regular season, was held below 20 points for only the third time all season and struggled to establish position in the post against Boston’s rotating bigs.

“We knew they’d try to make it tough on Joel in the paint,” Mazzulla said. “Our goal wasn’t to stop him completely — that’s nearly impossible — but to make him work for every touch and limit his second-chance opportunities. We did that well tonight.”

Philadelphia’s supporting cast failed to compensate. James Harden, returning from a left foot injury that limited him to 31 regular-season games, managed only eight points on 3-for-12 shooting. Tobias Harris added 14 points but shot 5-for-13. No other Sixers player reached double figures.

Bench Production Fuels Celtics’ Depth Advantage

Boston’s bench outperformed Philadelphia’s reserves by a margin of 38-16. Payton Pritchard led the way with 15 points off the bench, including four three-pointers, while Sam Hauser added 12 and Kristaps Porziņģis, making his playoff debut after missing the final 25 games of the regular season with a left calf strain, contributed eight points and five rebounds in 18 minutes.

Porziņģis’ availability was a significant boost for Boston, giving the Celtics a legitimate seven-footer who can stretch the floor and protect the rim. His presence allowed Robert Williams III to play fewer minutes without sacrificing interior defense, and the Celtics outrebounded Philadelphia 48-34 overall.

“Having Kristaps back changes how One can rotate,” Mazzulla said. “He gives us versatility — we can go big, we can go small, and he can hit shots from anywhere. That flexibility is huge in a seven-game series.”

What This Means for the Series

The Celtics now hold a 1-0 series lead and return to TD Garden for Game 2 on Tuesday, April 23 at 8:00 p.m. ET (00:00 UTC). A win in Game 2 would deliver Boston a commanding 2-0 lead and home-court advantage throughout the series, a significant edge given their 35-6 home record this season.

For Philadelphia, the challenge is clear: adjust offensively to counter Boston’s switching defense and find ways to get Embiid more efficient looks in the post. Sixers head coach Nick Nurse acknowledged the need for better ball movement and off-ball movement to break down Boston’s facilitate defense.

“We have to make them work harder on defense,” Nurse said after the game. “Too many stagnant possessions, too many contested jumpers. We need to move the ball with purpose and get Joel involved earlier and more often.”

The Celtics, meanwhile, aim to maintain their defensive intensity while continuing to get balanced scoring. With Tatum and Brown capable of taking over games and Holiday and White providing elite perimeter defense, Boston enters Game 2 with confidence — but without complacency.

As the series shifts to Philadelphia for Games 3 and 4, the Sixers will look to protect their home court and force a return to Boston. But after Game 1’s lopsided outcome, the Celtics have sent a clear message: they are not just ready to win this series — they are intent on dominating it.

The NBA playoffs are a marathon, not a sprint. But in Boston, the first leg was run at sprint pace — and the Sixers are now chasing.
