I have always told our kids for years that if a ref makes a call that makes them lose the match, well they shouldn't have put themselves into that position that a judgement call ends their day.
I still think that is a good way to think of it.
But with that being said thee are so many 1-2 point matches this time of year that does throw a curve ball into that thought process. We all have been on both sides of the coin with a judgement cal.
This is a horrible thing to happen to a coach/father at this time of the year. Lets all hope that the appeal process works and that many years of USW support and great service is taken in consideration over one call made in the heat of the moment.
I would think there is something to be learned by this incident, but to deny a coach/father from being able to watch his kid(s) at state seem to be extreme for a (I assume) a first time offense.
Just my opinion
