Celtics coach Joe Mazzulla is a former high school soccer standout who still studies the game religiously, both as a fan and to find concepts he can use in basketball. Mazzulla had extensive coaching conversations with Gasperini about the quests to create advantages in their sports. “It was cool,” Mazzulla said. “We got to watch film of both teams and show, ‘OK, here’s what this looks like as a basketball possession.’ Then we showed some of the differences. It was just fun. It was great continuity, great conversation, great to have that feel. You have two programs that are really trying to achieve something.”
