Mazzulla Uses Claude Daily to Rework Celtics Coaching Processes

He treats the AI as a conversational tool that surfaces research, prompts questions, tests film-room habits, revisits practice time allocation for greater efficiency.

Overview

  • Mazzulla confirmed Friday that he uses the Claude platform every day as part of his coaching routine to brainstorm and organize ideas rather than to make final decisions.
  • He is using Claude to audit specific workflows including pregame and halftime film sessions and the setup of the film room to improve how players learn and retain game plans.
  • The coach ran cross-sport comparisons with the AI, asking it to map similarities among soccer, handball and basketball to generate five-on-five practice ideas and communication techniques.
  • Mazzulla also had Claude review past practice plans to check whether time spent on priorities matched their importance, citing an example where offensive rebounding took roughly 5 percent of a practice plan.
  • Reporters note the adoption fits Mazzulla’s experimental, process-driven style and that while the tool changes how he prepares, any direct impact on on-court results remains unproven at this stage.
