it isnt cool that it happened, however, being a family member of an opposing player in the other arena.....u shouldnt have to, but reality is, u have to expect things like this from time to time, especially in the playoffs where the fans are more vocal, invested, intense, and sometimes intoxicated.
not condoning it by any means, but you have to have the mindframe that these things might happen and have a gameplan for when it does.
