With long-time assistant Micah Shrewsberry headed to Purdue University to be their head coach, the Celtics hired Joe Mazzulla as an assistant, according to Adrian Wojnarowski.
Mazzulla played for West Virginia University from 2006-2011 and left an assistant coaching job at Fairmont State to become an assistant coach for the Maine Red Claws in 2016. He reportedly impressed the Celtics coaching staff enough to earn a spot on the staff.
He returned to Fairmont State two years ago to become their Head Coach, but will now enter the NBA coaching ring as a 30-year-old.
The Celtics' coaching staff will most likely have a different task in front of them than last year. With Kyrie Irving and Al Horford likely headed elsewhere this summer, Boston will enter the 2019-20 season as a young underdog team with a fraction of the expectations the team faced last year.
Still, with the amount of youth that will be featured on the court, having a younger coach on the staff could go a long way in rebuilding a healthy locker room.
