The full video (
see here) shows the ref getting into a verbal spat with the coach, apparently because the coach slammed a door in protest of a call or something? The ref waves the coach to leave, and the coach is a few steps toward the door when he comes back toward the ref. You see the rest of it here -- he closes on the ref in a confrontational way, the ref holds his ground and shoves him back/down, and the coach pops up swinging.
edit: per the other thread, apparently the coach spit on the ref which is what provoked the shove.
The coach should
absolutely be banned from the association, permanently. You've got a kid stick-tapping while his coach tunes up a ref... that's beyond disgraceful. The whole world saw this, let alone the message it sent to the kids on that team. There's simply not a place in youth sports for someone who would be involved in that kind of situation.
Ref should also receive some re-training. Holding his ground and shoving the coach was a stupid move on his part. It's a youth game, not the NHL... there are no "messages" to be sent to the coaches. All he needed to do was back up a few feet and continue to wave the coach off, and the situation would never have escalated to the point of punches. Worst case, the coach makes an ass out of himself standing in open ice yelling.
