The Celtics are making major changes to their organizational structure. After 18 years in charge of the front office, Danny Ainge will step down from his GM role. Replacing him as the head of basketball operations will be Brad Stevens, who served as Boston's coach the past eight seasons, as reported by ESPN's Adrian Wojnarowski. The team will now search for a new coach.
