Losing 100-0 definitely isn't a confidence booster but what goes around comes around and that's what must be remembered. Throughout your time playing athletics you are going to be on both side of these beatings and I really see no reason to forfiet a game. At least 100 points is a common occurrence in basketball if you want to see a real beating check out when Slovakia beat Bulgaria 82-0 in an Olympic hockey qualifying event.
