Wyc Grousbeck says he blocked Danny Ainge from bringing Joe Mazzulla to Utah

Danny Ainge and the Utah Jazz took one assistant coach from the Celtics this summer when they hired Will Hardy to be their head coach.

Apparently they wanted to take a second, too. Appearing on The Greg Hill Show Tuesday morning, Boston owner Wyc Grousbeck revealed that Ainge also wanted to bring Joe Mazzulla -- whom the Jazz had also interviewed for the head job -- to Utah to be part of Hardy’s staff.

Grousbeck said he stepped in to block the move. And it’s a good thing he did, because Mazzulla is now the Celtics’ interim head coach following the suspension of Ime Udoka.

“I prevented Danny from stealing him this summer, because I told Danny I’d fly to Utah and personally strangle him if he did. You can quote that,” Grousbeck said. “You can take one person, an assistant, and make them a head coach, which they did with Will Hardy. Then they also wanted Mazzulla, and I was like, ‘That’s it, you’re crossing the line, and we’re not having it.’ And that was just when Joe was senior assistant with us, and now all of a sudden he’s interim head coach.”

This will be the first NBA head coaching job for the 34-year-old Mazzulla, who had been an assistant in Boston since 2019. It could be a daunting task taking over a championship-caliber team, led by stars, from a popular coach whose ability to connect with players and hold them accountable was clearly a key factor last season.

However, Grousbeck says he sees a lot of those characteristics that made Udoka successful in Mazzulla, including how he connects with players.

“That’s a really interesting point you made about relating to Ime. I think that there’s a lot of relationship as well, very naturally, with Joe,” Grousbeck said. “Joe’s a point guard out of West Virginia. Really tough is the first word that comes to mind, but focus-driven, super smart. He’s got nuclear energy. He’s almost like -- I don’t know why I would say this -- a mini-KG [Kevin Garnett]. He’s not a mini-KG. He’s very different from KG in a lot of ways, but just the intensity of the eyes is all I’m really thinking of right now. He’s not a Hall of Famer or anything like that, but he’s got intensity.

“For being a small-sized guy, point guard, assistant but never a head coach in the NBA -- now he’s interim head coach of the Celtics -- it’s a big ask for a 34-year-old. Except then you meet Joe Mazzulla and you’re like, ‘All right, this could really work.’ … We believe in him, and I think the players believe in him for sure.”
