Throughout the workout, Celtics assistant coach Tony Dobbins guarded Tatum pretty aggressively, while Craig Luschenat, the team’s head of player development, directed traffic. Dobbins guarded Tatum with an undeniable level of physicality — hand-checking him, and poking the ball out of his hands at times. (For reference, Dobbins was named the French League’s best defender three times in his EuroLeague basketball career — and while he wasn’t going all out, he was certainly upping the pressure).
Steve Tchiengang, one of the Celtics’ player enhancement coaches, partook in drills as a screener and passer, as did Tatum’s former Duke University teammate, Celtics assistant coach Amile Jefferson. Tatum’s trainer, Nick Sang, took the floor to watch.
