Momentum in the NBA postseason is often discussed as an intangible force, something that cannot be quantified but can be felt the moment a team begins to believe in itself. Right now, no team in the league is carrying more of that energy than the Philadelphia 76ers, who arrive in the second round of the 2026 NBA Playoffs riding one of the most dramatic series wins in recent league history. After falling behind 3–1 against the Boston Celtics, the Sixers authored a comeback that places them among just fourteen teams in NBA history to recover from that deficit, punctuating the turnaround with a 109–100 Game 7 victory on the road that has completely reshaped the Eastern Conference landscape.
That win did more than eliminate a rival. It redefined expectations for a team that had been facing serious questions only days earlier. Down 3–1, the Sixers looked like a group on the verge of another early postseason exit. Instead, they found a different gear—one built on defensive discipline, offensive balance, and a renewed commitment to playing through their core identity. The result is a team entering the next round not as a survivor, but as a legitimate threat.
The context surrounding that Game 7 victory is impossible to ignore. Jayson Tatum, the Celtics’ franchise cornerstone, was a late scratch due to left knee stiffness, a development that dramatically altered the balance of the matchup. Tatum had played through the first six games of the series while still managing the long-term effects of a 2025 Achilles injury, and his absence left Boston without its primary offensive engine in the most important game of the season. The Celtics shot just 40 percent from the field in the finale, struggling to generate consistent scoring under playoff pressure.
But reducing the Sixers’ comeback to that absence would miss the larger story. Philadelphia still had to win three consecutive elimination games, including two on the road, against a team with championship expectations. That does not happen by accident. It requires execution, composure, and a willingness to embrace the moment when everything is on the line. The Sixers delivered all three.
Now, that momentum carries directly into a second-round series that begins tonight against the New York Knicks at Madison Square Garden, one of the most demanding environments in basketball. Game 1 tips off at 8:00 p.m. ET, setting the stage for what is expected to be one of the most competitive matchups of the postseason.
From a structural standpoint, this series presents a fascinating contrast in styles and strengths. The Sixers enter with a high-powered offensive core that appears to be peaking at the right time, while the Knicks counter with physicality, depth, and a defensive mindset designed to disrupt rhythm and force opponents into uncomfortable possessions. The regular-season series between these teams ended in a 2–2 split, with the road team winning all four games, a detail that adds another layer of unpredictability to what is already a tightly balanced matchup.
At the center of Philadelphia’s offensive resurgence is Tyrese Maxey, who has emerged as one of the most dynamic guards in the league. Averaging 26.9 points per game in the first round, Maxey has become the Sixers’ primary pace-setter, capable of turning defensive rebounds into immediate transition opportunities and breaking down defenses with his speed and creativity. His ability to control tempo will be a defining factor in this series, particularly against a Knicks defense that prides itself on limiting penetration and forcing contested shots.
New York is expected to assign Mikal Bridges to that challenge, a matchup that could determine the rhythm of the entire series. Bridges’ length and defensive instincts make him one of the league’s most versatile perimeter defenders, but containing Maxey over the course of a full series is a different challenge altogether. If Maxey continues to play at his current level, the Knicks will be forced to adjust, potentially opening opportunities for other Philadelphia scorers.
In the frontcourt, the spotlight shifts to Joel Embiid, who delivered a dominant 34-point performance in Game 7 against Boston and appears to be rounding into peak form at exactly the right time. Embiid’s presence changes everything for Philadelphia. His ability to score in the post, draw fouls, stretch the floor, and control the defensive glass gives the Sixers a foundational advantage that few teams can match.
The Knicks will attempt to neutralize that impact with a physical rotation featuring Karl-Anthony Towns and Mitchell Robinson, a combination designed to challenge Embiid’s positioning, limit second-chance opportunities, and force him into difficult shots. This is not simply a battle of skill; it is a battle of endurance, discipline, and physical presence. Over the course of a seven-game series, those elements tend to matter just as much as scoring totals.
Beyond the headline matchups, the depth and adaptability of both teams will play a critical role. Philadelphia’s supporting cast demonstrated resilience throughout the comeback against Boston, with key contributions coming from multiple positions as the series progressed. That balance will need to continue against a Knicks team that thrives on forcing opponents into predictable patterns and exploiting weaknesses through sustained pressure.
For New York, the advantage lies in consistency and structure. The Knicks have built their identity around defense, rebounding, and efficient half-court execution, creating a style that can frustrate even the most talented offensive teams. They are comfortable playing close games, comfortable grinding through possessions, and comfortable turning small advantages into decisive runs. Against a Sixers team riding emotional momentum, that steadiness could become a critical factor.
The schedule for the series underscores the intensity of what lies ahead. Game 1 takes place tonight in New York at 8:00 p.m. ET, followed by Game 2 on Wednesday, May 6 at 7:00 p.m. ET, also at Madison Square Garden. The series then shifts to Philadelphia for Game 3 on Friday, May 8 at 7:00 p.m. ET and Game 4 on Sunday, May 10 at 3:30 p.m. ET, creating a rapid sequence of games that will test both teams’ depth and recovery.
For the Sixers, the challenge is not simply to carry momentum forward, but to translate it into consistent execution against a fundamentally different opponent. The Celtics series was defined by adjustments, resilience, and the ability to respond under pressure. The Knicks series will demand a different kind of discipline, one that emphasizes patience, shot selection, and defensive accountability.
What makes this moment particularly significant is the way it reflects the broader evolution of the Philadelphia roster. This is not a team relying on a single star to carry the load. It is a group that has demonstrated the ability to adapt, to find scoring from multiple sources, and to maintain composure in high-pressure situations. That balance is what allowed them to complete the comeback against Boston, and it is what gives them a legitimate chance to advance further.
For fans across New Jersey and the greater Philadelphia region, this series represents more than just another playoff matchup. It is a continuation of a season that has already delivered one of the most memorable turnarounds in recent NBA history. It is an opportunity to watch a team that has rediscovered its identity at the most critical point of the year. And it is a reminder that in the postseason, belief can be just as powerful as talent.
