True champions and winners don't make excuses. They don't talk about being sick, bad refs, poor coaching decisions.
Teach your kid to deal with realities of life and to overcome certain bad situations-don't keep showing a tape of where "_We" got ripped off. Don't keep telling your kid how a coach screwed up; don't make excuses for defeat-use them as positive learning experiences-
too many Dad's and Mom's after states have concentrated on the wrong thing-praise your kid; teach him to deal with defeat-don't place blame
