The Boston Celtics are gearing up for the 2026-27 season with five players facing significant pressure to perform following the trade of star Jaylen Brown. The team's official Media Day announcement sets the stage for a campaign where internal development will be vital for championship aspirations.

Following the major roster shift that sent Jaylen Brown elsewhere, the spotlight intensifies on several returning Celtics. Five specific players are now under the microscope to elevate their games and fill the void. Their performance on both the perimeter and in the paint will directly impact Boston's offensive efficiency and defensive rating. This internal challenge forms a central narrative for Head Coach Joe Mazzulla's squad as they look to maintain their status as Eastern Conference contenders.

Coach Mazzulla himself expressed clear excitement about his lineup decisions during last season's playoffs.

As the new season approaches, the Celtics' focus is on integrating their roster and defining new identities. The true test begins when the ball is tipped for real.
