There was one game that was well attended by coaches - the Brine All Star 2017-2018 game. There were at least a dozen coaches.

As far as I can tell, the people handing out jerseys did not pay attention to the pre-printed rosters for any of the Brine All Star games so what good it did to have college coaches on the sideline without being able to identify players . . . definitely better attended than the Warrior All Star game.
