Mazzulla and Brown set family-first tone

Boston’s training camp looks different this year: no Horford, Holiday, or Porzingis, and Jayson Tatum rehabbing his Achilles. Instead, Joe Mazzulla and Jaylen Brown are steering a youthful, high-energy group led by newcomers like Anfernee Simons and Chris Boucher.

The vibe? Coaches shouting, players sprinting—basically an intense family reunion where nobody’s allowed to sit down.
