76ers head to Boston for penultimate preseason game as Nick Nurse tests his rotation

The Philadelphia 76ers will close in on the final stretch of their preseason schedule when they head to Boston for a penultimate tune-up against the Celtics, a matchup that will put more emphasis on roster evaluation than regular-season stakes. With Philadelphia splitting its first two preseason games, the trip offers coach Nick Nurse one more high-visibility chance to sort through rotations and player roles ahead of the final days of exhibition play.

For the Sixers, preseason is where the coaching staff looks for reliable combinations and habits that can carry into the regular season. Against a Celtics team known for structured execution, Philadelphia can test whether its planned defensive matchups and offensive rhythms hold up when the work gets harder and the looks get more specific.

Nick Nurse’s presence typically raises the bar for how quickly lineups must execute both end-to-end. As Philadelphia moves toward the end of the exhibition window, the focus is likely to shift toward tightening lineup consistency, narrowing the group of primary rotation players, and giving clearer definitions to roles like ball-handler, secondary creator, and defensive assignment anchor.

The Celtics matchup also matters because it compresses the timeline for decisions. By the time teams reach the final two preseason games, coaching staffs generally have a clearer picture of who can contribute within the team’s preferred style, who fits best in smaller or larger lineups, and which bench groups can stabilize stretches when the starters rest.

Philadelphia’s first two preseason games, according to the team’s reported preseason progression, ended in a split result, suggesting that some things have clicked while others still need refinement. That makes the Boston game especially important as a measuring stick. It is not about any single result, but about whether the players who are pushing for clearer minutes show growth in execution and decision-making.

Even in preseason, matchups against quality opponents can reveal whether a team’s identity is taking shape. For the Sixers, the Celtics game should clarify how well their rotations communicate, how effectively they defend without losing their assignments, and how consistently they can generate good looks under pressure rather than relying on early advantages.

With this being Philadelphia’s second-to-last preseason contest, the next step is straightforward: follow up in the final exhibition game with cleaner execution and more predictable lineup patterns, rather than experimenting broadly. The most important question going forward is which groupings Nurse trusts when the game tightens, since those are the combinations that tend to reappear once the regular season begins.
