The Boston Celtics are rolling into the 2026-27 preseason on a high, fueled by a perfect 5-0 winning streak and a flurry of positive camp storylines. Head coach Joe Mazzulla is finalizing his rotations as veterans and new faces jockey for roles.
Jayson Tatum's evolving leadership is a central theme. Multiple reports detail his growing voice behind the scenes, a development the team has needed. His mindset about the roster has also sparked conversation, with some analysts believing his confidence is a major positive.
New acquisition Mitchell Robinson is generating significant buzz. The big man has spoken about expanding his offensive game to the perimeter, a change that could unlock new dimensions for Boston's attack. His departure from the New York Knicks left a void they admit will be hard to fill.
Payton Pritchard is another name on everyone's lips. Seen by many as the NBA's most obvious breakout candidate, he's reportedly shown marked improvement. Questions about a potential contract extension for him are already circulating.
Moving Jaylen Brown to the Philadelphia 76ers was a franchise-altering decision. But early analysis suggests the Celtics might have improved their overall balance. The addition of two-way players and shooters like Baylor Scheierman, who has impressed early, aims to fill the scoring gap.
The official 21-man training camp roster is set, featuring a mix of established stars and hungry competitors. Several players, including those in new roles, are under pressure to prove their worth this season.
Veteran guard Mike Conley is expected to provide stability. He's embracing a dual role as both a player and a de facto coach on the floor, which will be vital for a team integrating new pieces.
Boston's form is scorching hot. This offensive explosion provides a powerful foundation as they enter preseason preparations.
Coach Joe Mazzulla faces some immediate decisions, like how to manage Mitchell Robinson's minutes in late-game situations. The potential for training camp battles at several positions is real, which should raise the team's competitive level.
While external power rankings are beginning to slot the Celtics among the East's elite, the internal focus is on daily progress. With a blend of veteran savvy and emerging talent, the goal is to convert this preseason buzz into sustained regular-season success. Their upcoming schedule is available on our schedule page.
