Joe Mazzulla hits Celtics with disclaimer warning on high training camp vibes

Boston Celtics head coach Joe Mazzulla delivered a message to his team during training camp ahead of the upcoming 2026-27 NBA season. Mazzulla, in his fifth season with the team, led the Celtics to a championship in 2024 and won Coach of the Year last season. However, he aims to prove critics wrong after underwhelming results in the postseason.

During a press conference with reporters, Mazzulla cautioned the team about the high morale at training camp, warning them not to get too comfortable. "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," he said.

Mazzulla emphasized that these qualities cannot be simulated; they come with experience and adversity. He cautioned that despite the positive vibes at training camp, the team needs to face challenges to discover their true potential. "And you can’t simulate those. It just comes with time. And so, right now I would say all 30 teams fell great about themselves, and we got to wait till adversity hits.

And adversity is even a strong word. There’s nothing really adverse about playing in the NBA. But we got to wait until stuff doesn’t go your way, and then you got to figure out who we are and how we’re going to be at out best."
