Who's at fault, the parents or the coach?

[Shadowrun]

I happen to have a 12 yr old brother (so he is a bit older then the kid in the story).

My Mom would rush to him and offer him a juice box/snack, ask him if he is all right, generally comfort him, make sure he is okay.

My Dad would probably go to the coach ask him what happened and if the kid deserved it.
If Ricky (my brother) did do something my Dad might give a talk about controlling your temper/anger/behavior etc.

If Ricky did something like the defender did here, he has to understand that is not okay. http://winningtheturnoverbattle.blog...k-mr-roby.html

If the coach was in the wrong, my parents would ask for a personal apology to them (definitively not on a website). My parents would never sue in this case (no one was hurt), worst that would happen is they ask him to be moved to a different team.
