Boston Celtics coach Joe Mazzulla is building trust with his players through relentless offseason effort. During the first week of June, Mazzulla was spotted in both Omaha, Nebraska, and Lisbon, Portugal, while supporting Baylor Scheierman and Neemias Queta, respectively. That's roughly 4,400 air miles between the two spots -- with no direct flights -- and is only the start of Mazzulla's worldwide travels aimed at building trust with his players. Mazzulla's players have bought in largely because of his old-fashioned relationship building. 'He is very unpredictable,' Al Horford said. 'People see all these other things. But there's also, I feel, like the caring factor from him, and it's a real thing.' Horford suggested Mazzulla might even go to great lengths to hide that more human side. 'One of the coaches that was [in the Dominican] told Joe that he wanted him to give another session, another practice,' explained Horford. 'So, the next day, we go see the president and we have our moment and everything. And then Joe kind of afterwards, we drive separately, we go our separate ways. And he went back to the neighborhood in the Dominican, in La Romana specifically, it's a city there. And he went back and gave -- he's not gonna talk about this, nobody knows this -- but he gave like a two-hour clinic to a bunch of kids down there. And he just went down there with the people and just gave a free basketball clinic and just talked about fundamentals of the game. So, it just speaks of the type of great person and leader that he is.'
