Joe Mazzulla has earned a reputation for saying exactly what he thinks, and that tendency was on full display after the Boston Celtics survived a physical test in late March and again when he was asked about one of the NBA's annual awards.
The Celtics squeezed through a game in which Mazzulla said his team's effort was never a question but its execution lagged for the first three quarters. "I thought our effort was there throughout. I thought our execution was poor," he said. "They put a ton of pressure on you with their full-court pressure the entire time. We had 13 turnovers for 23 points and we had a couple uncharacteristic ones on some live ball ones."
A single timeout flipped the game. Mazzulla credited an in-huddle reset that produced the kind of late-quarter stretch Boston has demanded from itself this season. "I thought our execution just got better after that timeout. We executed offensively. I thought we executed our individual defense. Eighteen offensive rebounds to close the game with six offensive rebounds is big time. They tested us and we have to be able to answer the challenge and I thought our guys did."
Jaylen Brown sat for meaningful chunks of the fourth quarter, giving Mazzulla a chance to experiment with lineups Boston has rotated more aggressively this spring as it hunts for playoff combinations.
"Yeah, I mean I think it's just we've developed different — everybody can impact winning and we've developed different identities and lineups to be able to go to," Mazzulla said. "We just have to have trust in one another that we can impact winning and I thought that just that lineup hadn't played the game and I wanted to just give a different feel to a segment of the game."
Boston's backcourt depth was a particular focus. Mazzulla credited Derrick White for doing more than showing up on the scoresheet. "I just trust him to figure out. He's going to make plays. He's always going to wake up because it's not just the scoring. He had two offensive rebounds at the end of the game. He had a couple blocks. He had the steal. He's always going to figure it out."
He also saved praise for Luca Garza, who handled the dirty work against a frontcourt that made physicality its calling card. "He was great on both ends of the floor. Great defensively. Great offensively. He does a great job screening. They play a hectic style. They put a ton of pressure on you from a physicality standpoint, and you have to be able to read and make plays and play through physicality."
Boston then entered April pushing through another tough spot when Mazzulla was asked about Coach of the Year chatter. He did not hedge.
"I don't need it," he said. "I think it's a stupid award. They shouldn't have it. And it's more about the players. It's more about the work the staff puts in. It's just that simple. I really don't ever want to be asked or talked about it again. It's just that dumb. So, the players play. It's about them. Staff works their ass off. I'm grateful to have them."
The bluntness is consistent with how Mazzulla has approached the second season following Boston's 2024 championship. His public messaging has pushed every piece of recognition back toward the locker room, and his in-game decisions — shuffling lineups, cutting rotations in late-close games, demanding execution even when the effort is already there — have given the Celtics a framework that is clearly playoff-built.
Boston's matchup outlook is clearer than most in the East. The Knicks, Cavaliers and Pistons have each shown ability to push the Celtics around for stretches. Mazzulla's commentary from March suggests his team will enter the postseason with a simple philosophy: execute late, trust the lineup next to you, and ignore the plaques.
