Boston looked ready to close this series until Joel Embiid stopped playing it on the perimeter. In Philadelphia’s Game 5 win, Embiid dragged the matchup back into the paint, and that changed the terms of everything.
Boston’s preferred version of the series is slipping
The Celtics were comfortable when Embiid’s return in Game 4 came with rust and jumpers. That version of the matchup let Boston stay spread, pressure the ball, and trust its depth. Game 5 was the opposite. Embiid posted up, hunted contact, and forced Boston to absorb him where it is least convincing.
He finished with 33 points in 39 minutes, and the number only tells part of the story. The more important shift was where those touches happened. He stopped floating beyond the arc and started living at the foul line, on the block, and in the short middle, where Boston’s smaller counters become much harder to hide.
The fourth quarter showed the real pressure point
Philadelphia’s defense deserves part of the credit, but Boston also looked rattled by the need to score through a set defense after its own half-court flow disappeared. The Celtics scored just 11 points in the fourth quarter and missed 16 straight shots. That kind of collapse does not happen in a vacuum.
When Embiid is healthy enough to anchor both ends, Boston has to work harder for clean looks and also has to defend without a true answer for his size. That double strain is what turned a routine closeout into a live series again.
Philadelphia finally has a real interior chain reaction
The Sixers are not just getting Embiid scoring. They are getting a shape to the offense. Tyrese Maxey’s 25 points, 10 rebounds and five assists landed differently because Embiid’s presence bent the floor first. Boston could no longer load up the same way without giving up deeper catches, fouls or kick-out openings.
That is why Game 6 is not really about whether Philadelphia can repeat the exact box score. It is about whether Boston can keep the series outside the lane again. If the Celtics cannot, then this stops being a simple talent-and-depth matchup and becomes a durability test against one player who still changes the geometry of a playoff series when he is upright.
