The Philadelphia 76ers enter the 2026-27 NBA season with a championship-level roster but a major puzzle for head coach Nick Nurse to solve. Their preseason form, including a heavy 144-106 loss to the Boston Celtics on October 10, highlights the work ahead. After an aggressive summer that brought in LeBron James and Jaylen Brown, the Sixers must figure out how all their talent fits together.

Philadelphia completely reshaped its core this summer. Paul George, Quentin Grimes, Kelly Oubre Jr., and Andre Drummond are out. The team acquired Jaylen Brown in a trade with Boston and signed LeBron James to a two-year deal. James, 41, averaged 23.2 points, 7.3 assists and 6.7 rebounds last season for the Lakers. His playmaking could ease the load on Tyrese Maxey and Joel Embiid. But the departure of role players like Grimes and Oubre removed valuable defensive depth and athleticism from the bench.

The Sixers have tried to replenish that depth with signings like Kentavious Caldwell-Pope, Dean Wade, and Anfernee Simons. Simons could be a vital piece. He has shot 42.7% on catch-and-shoot three-pointers over the last six seasons. That specific skill is exactly what a team loaded with stars needs to create space. His ability to knock down shots without needing the ball will be tested immediately.

On paper, a lineup of LeBron James, Jaylen Brown, Tyrese Maxey, Joel Embiid, and second-year guard VJ Edgecombe is formidable. Edgecombe averaged 16.0 points and 4.2 assists as a rookie. The problem is usage. Analyst Dean Oliver described Philadelphia's five main offensive pieces as "super-users," with a combined career usage rate of 134%. There are only so many possessions in a game. Deciding when James, Brown, Maxey, or Embiid should initiate the offense is Nurse's biggest tactical question. It's a challenge of egos and rhythm, not talent.

Their preseason results show the process is a work in progress. After a 120-97 win over the New York Knicks on October 5, they lost 114-108 to the Brooklyn Nets on October 8. The Celtics exposed defensive communication issues and an offense that often looked disjointed.

The immediate focus is their next preseason fixture, a rematch against the Boston Celtics at home on October 16. It's a final chance to experiment before the regular season begins. The best-case scenario is that Nurse finds a rotation that maximizes each star's strengths. James could orchestrate, Brown could attack closeouts, Maxey could use his speed, and Embiid could dominate the paint. Simons and other role players must hit open shots created by the constant defensive attention on the stars.

The worst-case scenario is a season of friction where too many players need the ball. The loss of rebounders like Drummond could also hurt them when Embiid rests. Expectations are sky-high after last season's 45-37 record and Eastern Conference semifinals exit. The question is no longer about having enough talent. It's solely about making that talent work as a cohesive unit. Their preseason performances suggest they are still searching for answers.
