At this point in the game, I would go with ejections of the mascot and player rather than punishing the white team (who made a great shot to take the lead) with technicals for the actions of their fans.

Additionally, the gray team (team down 1 point) was able to make an offensive substitution due to the stoppage of play. I surmise that the gray team did not have any timeouts to get that player in the game, so despite the delay and perceived disadvantage had a fair chance to win the game.

FUN FACT EDIT: Before she hit that game-winning shot, white #1 was 1-16.
