The Boston Celtics expected Neemias Queta to be a steady, rising piece in their rotation this season. For long stretches of the regular season, he looked exactly like that — disciplined, reliable, and quietly effective on both ends of the floor.
But in the postseason, against the Philadelphia 76ers, that version of Queta has largely disappeared.
And now, Boston is facing an uncomfortable reality: their frontcourt problem might be bigger than they thought.
Regular-season promise, playoff collapse
During the regular season, Queta looked like a success story. His defensive positioning improved, his energy stood out, and he gave the Celtics valuable minutes as a traditional interior presence.
But in this playoff series against Philadelphia, that consistency has not carried over.
Instead, Queta has struggled with foul trouble, defensive discipline, and maintaining impact against elite opposition. He has had a couple of solid outings — including Game 1 and Game 5 — but the overall trend has been concerning for Boston.
The aggression that once made him effective is now working against him, pulling him off the floor too often and disrupting his rhythm.
Joel Embiid exposes the gap
The clearest issue has been the matchup problem created by Joel Embiid.
Against Embiid, Queta has been forced into uncomfortable defensive positions far away from the rim, where he is least effective. When Embiid steps out to shoot or pulls defenders into space, Queta’s limitations become more visible.
It has also exposed a broader issue: Boston’s inability to protect the paint without sacrificing spacing elsewhere.
Philadelphia has taken full advantage of that balance problem, collapsing the interior while daring Boston’s secondary shooters to beat them.
Not just Queta — a system issue emerging
While Queta has taken the most criticism, the Celtics’ frontcourt issues go beyond one player.
The lack of a true stretch big has allowed Philadelphia to tighten its defensive scheme. Boston’s spacing becomes predictable, and their primary scorers — Jayson Tatum and Jaylen Brown — are forced into congested driving lanes.
That’s where the series has started to tilt.
Even when Boston rotates other options into the lineup, the result hasn’t changed much. The issue isn’t just personnel — it’s structural.
A turning point for Boston’s long-term plans
The most important takeaway from this series is not just about winning or losing in the short term.
It’s about what this exposes for the future.
Queta may still be a useful rotation player, but this series is raising doubts about whether he can be trusted as a long-term starting center on a championship-contending team.
If Boston is serious about maintaining title expectations, they may need a more versatile, multi-dimensional big who can defend elite centers while also contributing offensively in space.
The reality check
Boston’s situation is still salvageable in this series. One strong performance can shift momentum quickly in the playoffs.
But even if they survive this matchup, the larger question remains unanswered.
Have the Celtics already seen enough to know what they are — and what they are not — in the frontcourt?
Because Philadelphia hasn’t just challenged them in a series.
It may have revealed a flaw they can’t ignore anymore.
