The Boston Celtics officially opened training camp for the 2026-27 NBA season following media day on September 28, 2026. The organization is currently recalibrating its team identity after the departure of long-time veteran Jaylen Brown.
Why it matters
The team must establish a new play-style and offensive rhythm to maintain competitiveness as younger players step into expanded roles. Adjusting to the vacancy left by Brown is the primary objective for the coaching staff as they prepare for the new season.
The Celtics roster features three centers in Mitchell Robinson, Neemias Queta, and Luka Garza. This transition marks the end of Jaylen Brown's 10-year tenure with the franchise.
The players
Jayson Tatum
He is an All-Star forward for the Boston Celtics who is entering the 2026-27 season at full health.
Jaylen Brown
He is a veteran basketball player who spent 10 years playing for the Boston Celtics before departing the roster.
Payton Pritchard
He is a guard for the Boston Celtics who began participating in team scrimmages at the Auerbach Center in August 2026.
The details
Coaches implemented a global training program with workouts held in the United States, Portugal, and Spain to engage players and foster team chemistry. While Jayson Tatum enters the season fully healthy, the team intends to adopt a faster, more open offensive approach.

Season Trajectory
This roster shift follows the pattern of the 2016 NBA offseason roster restructuring. The team is currently retooling its offensive structure to compensate for the loss of a primary contributor while integrating younger talent.
The transition to a faster offensive style with increased reliance on younger players will dictate the team's depth chart and rotation minutes throughout the season. Fans can monitor how the three-center rotation impacts rebounding and defensive efficiency in early games.
The takeaway
The Celtics are pivoting to a faster, more spaced-out offensive identity to maintain their competitive edge. Establishing chemistry early among the revamped roster will be critical to their success in the upcoming season.
