Joe Mazzulla said the Boston Celtics need time to process the trade that sent Jaylen Brown to the Philadelphia 76ers, speaking to The Athletic during Las Vegas summer league. Mazzulla detailed both his respect for Brown and the challenge of moving forward without him.
"There needs to be a grieving process for losing not just a player in Jaylen, but a person in Jaylen," said Mazzulla. "There needs to be a grieving process that this guy, what he has done on the court and what he's done in the community and what he's done for the city of Boston, there should be a grieving process. But the … gray area is throughout that loss, you're also gaining."
The Celtics acquired Paul George, Mitchell Robinson and Mike Conley as part of their offseason overhaul. Mazzulla said he plans to draw on the varied experiences those veterans bring to the locker room.
"We're getting three guys back," said Mazzulla. "One guy was a champion. So, we can leverage the experience that he had in the current moment of like, 'Hey, what worked for you guys? How can we learn from little stuff that you did?' And there's two guys that haven't (won a championship) yet. And how can we leverage, for lack of a better phrase, the hungriness or the desperation that they may have to try and get to that point?"
Mazzulla praised Robinson's defensive versatility, recalling Boston's approach to the center during a 2025 playoff series against the Knicks.
"I think his defense is underrated as well," said Mazzulla. "If you look at his ability to defend different types of (centers). Even two years ago, they were very comfortable putting him on (Kristaps Porzingis) and recovering back to his pops for his size. So, everyone's going to talk about the offensive rebounding, but his defensive versatility and his pick-and-roll defense is good."
Mazzulla also addressed comparisons between George and Brown, cautioning against viewing the trade as a direct swap of talent.
"Because there was a transaction between Jaylen and Paul George, it doesn't mean one's better," said Mazzulla. "No one's going to replace Jaylen Brown on our team and what he's done in the community. No one's going to do that. And we're not asking that to happen, but we need and I need as a coach and we need as a staff and we as a team have to demand the best of what Paul George can bring in because he's got a lot left."
Brown has expressed frustration over how the offseason unfolded, saying he felt disrespected by the organization before being dealt to Philadelphia. Mazzulla said he empathized with Brown's position throughout the process.
"Honestly, when some of the trade stuff was starting to happen, there were other guys on our roster that were impacted emotionally as well because their names were in it as well," said Mazzulla. "I think the thing that's different is obviously having a respect and an understanding of what Jaylen has done for the Celtics for 10 years."
Mazzulla also pushed back on speculation that Brown's comments last season about it being his favorite year hinted at tension within the organization.
"You can't base it off that," said Mazzulla. "There's people who are going to (judge) the intention, but in those situations, you trust the intention of a guy that you've seen the character of every single day. And we've seen Jaylen's character, and we trust who he is."
