I think it's 3/6, Mavs @ Boston. Home game. Around his birthday. Primetime. NBA Finals rematch of 2 seasons ago. Cooper Flagg, a northeaster native who grew up cheering for the Celtics having a homecoming. Think about the revenue that will generate.
It won't make any sense coming back during a very tough road trip.
3/14 against the Wizards isn't primetime enough albeit it's a game to ease in to. Anytime after I question if he should even consider coming back or just sit out for the seaosn. But that documentary is something else to consider otherwise.
