Jay Larranaga and Jamie Young not returning to Celtics coaching staff

With reports that Will Hardy will be one of new head coach Ime Udoka’s lead assistant and the potential of adding Damon Stoudamire to his staff, it appears as though several longtime assistants under Brad Stevens will not be retained by the team.

Per The Globe’s Adam Himmelsbach, Jay Larranaga and Jamie Young will not have their contracts renewed and will not return.

After being courted for several head coaching jobs in college and the NBA (including being a finalist when Doc Rivers left Boston), Larranga leaves the Celtics after spending seven years as Stevens’ lead assistant. He’s often credited for shepherding the careers and development of players like Marcus Smart and Robert Williams.

Young spent two decades with the Celtics, first as a video coordinator and then spending time on the bench with Jim O’Brien, Doc Rivers, and Brad Stevens.

“The experience was incredible,” Young told Himmelsbach. “You don’t usually get to be in one place this long in this business. It was everything anybody could’ve wished for. Seventeen years in the playoffs, five Eastern Conference finals, two Finals, and one championship.”

However, league sources tell The Globe that Udoku will retain former Stevens assistant Joe Mazzulla. Mazzulla joined the Celtics two years ago after coaching stints in college and the Maine Celtics.
