Joe Mazzulla isn’t pretending the Celtics’ smooth start means much just yet.
With Boston moving into a new era after trading Jaylen Brown, the mood around the team has stayed upbeat in training camp. The Celtics still believe they can compete, and that energy has shown up early. But Mazzulla, as usual, isn’t interested in getting carried away.
He made clear that the real test won’t come until the season starts and the first wave of problems arrives. In his view, every team feels connected before the grind begins.
“Every team you lead is the most together team right now. Because we haven't traveled.
No one's gotten benched. No one's been on a losing streak.
No one's gotten blamed in the media. No one's had to go stand in the corner for 10 minutes and not get the ball.
So, you learn those things as the season goes on, and you just learn how to work through those things together,” Mazzulla candidly said about how things can change when an NBA season starts.
He added, “You can't simulate those. It just comes with time. So, right now I would say all 30 teams feel great about themselves, and we got to wait till adversity hits.”
That outlook fits the Celtics’ current situation. The 2026-27 Eastern Conference picture is crowded, with the defending champions New York Knicks being talked about as favorites along with the refreshed Miami Heat and the stacked Philadelphia 76ers.
Boston still has talent, but it no longer has the same star power after splitting up the two Jays. Jayson Tatum’s co-star is now Paul George, who is older and has not been at that elite level for a couple of seasons now.
For now, though, the Celtics’ camp has been productive and positive. Mazzulla’s message is simple: the good vibes matter, but only for so long. Eventually, the season will reveal how this group handles the tough stretches.

Jayson Tatum Sees One Immediate Difference With Celtics Big Man
Mitchell Robinson is already giving the Celtics something they have long valued in the frontcourt, and Jayson Tatum noticed the difference quickly. After signing a three-year contract with Boston, Robinson brings a reputation for defensive disruption, physical rebounding and the kind of interior presence that can change how opponents attack the rim.
Tatum pointed to Robinson's defensive skills, his work on the glass and the broader impact he can have on the group, which fits neatly with what Boston has wanted from its big men. Robinson has built his name as one of the league's better offensive rebounders, and the Celtics will be counting on that edge to show up every night, especially once the games start to tighten and the margin for error gets smaller.

Jayson Tatum Already Sounds Comfortable With A New Celtics Frontcourt Fit
Bostons final training camp practice in Charleston, South Carolina, offered a first real glimpse of how Jayson Tatum is beginning to mesh with a new frontcourt partner. With the season inching closer, Tatum spent some time discussing Mitchell Robinson and the way the Celtics can lean into his defensive presence, rebounding and screening to make the half-court offense and the overall lineup structure feel more natural.
For Tatum, the fit appears to be about more than just rim protection. He sounded comfortable with the idea of Robinson helping set the tone on both ends, and that matters for a team trying to sort out its rotations and maximize the forwards and centers around him. The early read is encouraging, even if the real test will come once the Celtics start facing live pressure and have to turn those camp impressions into something repeatable. [Read more 🡒]
Celtics Are Suddenly Linked To A Knicks Move Fans Didn't Expect
The Celtics already made one notable Knicks-related splash this offseason by bringing in center Mitchell Robinson, and now their front office is being tied to another big name from New York. This time it is Karl-Anthony Towns, whose contract situation has quietly become a talking point around the league as Boston looks for ways to keep stacking talent around its core.
A Towns deal would not be simple and it would not come cheap, but the fit is easy to understand for a team that values spacing, size and versatility. The possibility only exists if contract talks in New York go sideways, which remains a long shot given the Knicks recent championship, but the mere mention of Boston in that conversation is enough to make the idea worth watching.
