Celtics Coach Joe Mazzulla Says He Uses AI to Review Practice Plans

Boston Celtics coach Joe Mazzulla says he uses artificial intelligence to review past practice plans and check whether the team’s stated priorities received enough time. The available reporting does not identify Anthropic’s Claude—or any other specific AI model—as the tool. Mazzulla described asking AI whether a previous season’s plan was efficient, using offensive rebounding as an example: if it accounts for only 5% of practice, he said, the schedule may not reflect the team’s stated emphasis.
