On Sunday night the Boston Celtics made the first move of their 2023 offseason, adding Sam Cassell to their coaching staff. While Cassell is the first addition to Joe Mazzulla’s staff this summer, he may not be the last.

According to Yahoo’s Jake Fischer, current Milwaukee Bucks assistant Charles Lee is  “on Boston’s radar for assistants behind head coach Joe Mazzulla.” Fischer added that Lee “remains involved in several situations.”

  • Lee, 38, is still currently employed by Bucks as an assistant, but it’s not uncommon to see assistant coaches leave an organization during a head coaching change (as Cassell did, going from Philadelphia to Boston). The Bucks fired Mike Budenholzer after their playoff exit last month, and hired Raptors assistant Adrian Griffin to replace him.

    Milwaukee is the second NBA organization Lee has worked for as an assistant coach. He joined the Bucks in 2018 after spending five years with the Atlanta Hawks.

    Prior to his time in the NBA, Lee began his coaching career as an assistant at his alma mater Bucknell, where he worked from 2012-2014. Lee also played at Bucknell, where he was the Patriot League Player of the Year in 2006. He played internationally from 2006-2010.

    As things stand now, the Celtics currently have four assistant coaches working under Mazzulla. That group includes Cassell, Anthony Dobbins, DJ MacLeay, and Matt Reynolds. The team recently lost three more assistants to Ime Udoka and the Houston Rockets.
