The Boston Celtics were surprisingly busy this offseason making a franchise-altering decision that sent All-Star forward Jaylen Brown to Philadelphia for Paul George. But now it’s time to switch focus to the Summer League and the young players that the Celtics will have on the court next week in Las Vegas.

The head coach of the Celtics 2026 Summer League will be assistant coach Amile Jefferson. It’ll be his first time coaching in Summer League, although he’s been on the team since 2023 under head coach Joe Mazzulla.
