The Celtics reportedly made a significant addition to coach Joe Mazzulla’s staff on Sunday, less than one week after the team’s Game 7 loss in the Eastern Conference finals.
Boston is set to add veteran assistant coach Sam Cassell alongside Mazzulla ahead of his second season, according The Athletic’s Shams Charania. Cassell, 53, has spent the last three seasons as an assistant with the 76ers under recently-fired coach Doc Rivers.
A 19-year NBA veteran and three-time NBA champion, Cassell will return to Boston 15 years after helping the club win its 17th ring with the famed 2008 Celtics. Cassell retired as a Celtic in 2009, and immediately went into coaching, working a combined 11 years as an assistant for the Wizards and Clippers before joining the Sixers.
