BRIGHTON - Media Day can be a strange little theater, all polish and predictability, but this one still offered a few useful clues about where the Celtics are headed. The answers were measured, the setting was formal, and yet the message came through: Boston believes its season is already underway, and the shape of it will be defined by depth, role changes, and a lot of internal competition.
Brad Stevens set the tone first on Monday afternoon, with Joe Mazzulla and then the players following in turn. Most of the usual Media Day scripts were there - summer updates, new-teammate chatter, the familiar questions about what comes next after the Jaylen Brown move. But the bigger picture was less about headlines and more about how the Celtics see themselves.
Stevens made that point clearly when he talked about roster construction and the players already in the building.
"It's not just who you bring in; it's also what guys can step into new roles and what guys can do to take the next step in their ability to impact [winning]," Stevens said. "And oftentimes that happens because you're younger and you get better; sometimes it happens because there's movement within the roster that allows for more opportunity.”
That line said plenty about how Boston is viewing this group. The Celtics think there’s more to get from the roster they already have, and that includes players who may be ready for bigger jobs.
Payton Pritchard is one obvious candidate for a larger role. So are the younger wings: Baylor Scheierman, Hugo Gonzalez, Jordan Walsh, and Ron Harper Jr.
Boston clearly believes there is more upside in the depth chart than the outside world may be giving it credit for.
Stevens also made it clear that depth is not some luxury item in the modern NBA. It’s part of the survival kit.
"I think that most coaches would tell you, especially when I was in college, would be like, 'I'm good with seven or eight guys, and we can figure out how to navigate it with the rest,' Stevens said. "But that's just not the way you can win in this league. So, I'm really interested to see how the depth not only is utilized as an advantage, but is also like, there's going to have to be some sacrificing at that level, for guys that have tasted a little bit of success at different times throughout the year."
That’s where this Celtics team starts to come into focus. They’re built to go 16 deep right now, and soon 17.
That means everyone is going to have a shot, but it also means the staff has a real sorting job ahead of it between now and October 20. Boston used that kind of rotation approach last year, and it sounds ready to lean into it again.
Mazzulla framed the challenge in his own way, focusing less on a fixed blueprint and more on what the team can become once camp gets rolling.
"How can we take advantage of the strengths and the talent that we have?" Mazzulla said.
"How can we take advantage of the offseason and the work that the guys have put in to become better players, and turn that into an offensive and a defensive philosophy? I don't know that I have that answer on day one.
I think your team naturally grows, and you're always learning about your team.
"And so, I think that's the point of training camp. Is, by the end of training camp, can we have a clear establishment of what our identity is as a team and what we look like on both ends of the floor? And then develop new ones as the season goes on based on the challenges that the season presents.”
That’s the real takeaway from a day that usually doesn’t give much away. Boston is not treating this as a reset so much as a process of discovery - who can handle more, who can sacrifice, and how all those pieces fit once the games start for real.

Celtics Preseason Will Be The First Test Of Bostons New Core
The Celtics are headed into preseason with a roster that already looks and feels different, and that alone makes October worth watching in Boston. After the trade that sent Jaylen Brown to Philadelphia, the team is set to open camp with Paul George, Mike Conley Jr. and Mitchell Robinson among the new faces trying to fit quickly into a group that will be judged almost immediately on how well the pieces come together.
Preseason games will air on NBC Sports Boston and stream on DIRECTV, giving fans an early look at how the new core functions before the real games start to count. The schedule also offers a first glimpse at the Celtics' opening run of regular season games, and with the training camp roster now set for 2026-27, this stretch should tell a lot about which roles are already taking shape and which ones are still very much up for grabs.

Mitchell Robinson Is Already Stirring Emotions Beyond Boston
Mitchell Robinsons move to Boston has already sent a ripple through the rest of the East, especially in New York, where the Celtics latest big-man addition now has to be processed as both a loss and a new challenge. Boston brought Robinson in on a three-year, $47.4 million deal after his role in helping the Knicks win the NBA Championship, making him one of the more notable changes to a roster that keeps trying to stay in the title mix.
The Knicks answered by bringing in veteran Andre Drummond on a one-year deal, a move aimed at filling the gap while keeping the frontcourt steady. Former Knicks teammates have sounded split on Robinsons exit, with some still feeling the sting of losing him and others taking a hopeful view of Drummonds arrival, which only adds another layer to a transaction that already carries more emotion than a typical free-agent signing.

Paul George Just Became A Real Celtics Decision Point
Paul George has become one of those names that can linger around a roster long after the obvious offseason chatter has moved on. An Eastern Conference executive recently suggested the Celtics could still find real trade value in him if he is healthy, which is notable given the contract and the long view Boston has to take with every major move. His deal still carries two years of salary commitment, so any discussion around him is as much about flexibility and timing as it is about talent.
The health piece is where the conversation gets complicated. George has played limited games in recent seasons, and Boston has not signaled any desire to move him, but that kind of uncertainty always changes how teams evaluate a players market. If he can stay on the floor, the Celtics may at least have a meaningful decision to make, especially if the return resembles the kind of protected first-round pick an executive believes is still possible.
