RCates, here is a hypothetical situation for you...you're a parent who is trying to teach your child that smoking pot is bad, and unacceptable behavior. But, wait, you remember that you smoked it when you were much younger. Based on YOUR earlier logic, you can no longer expect your child to not smoke pot, because you did it once (or more) at some point in your own life.
That is simply ridiculous.
As a parent, you can apply this to anything - just because you have made mistakes yourself, does not mean that you can no longer expect the proper behavior out of those under your responsibility.
If you think that every coach your child has should be, or is going to be, as good as Coach Savitz, you are setting yourself, and your child up for major disapppointment. NOW is the time you should be teaching your child that things are not always going to go his/her way - and, when things don't go the way you want them to, sometimes you just have to suck it up and move on.
Maybe you need to redirect your blame to where it belongs - with yourself.
