Not gonna try and defend the score, but I would be willing to bet that Coach Bill had placed restrictions on his players before they could score. Things like had to cross it or be a corner and other things that would slow down the scoring. Would also bet most of the later scores were by defenders playing up top or non starters who do not normally get to score.
Problem is they are a very very good team (have been for 4 years now) and instead of playing keep away for 3/4's of a game they let their players play. While it may seem harsh I think the losing team can lean alot from watching a good team like that play around them. I would think a 14-0 loss where they were challenged the whole game would be better than a 5-0 loss where the other team scored 5 goals and then played keep away for 40-50 mins, to me that is more like taunting than playing.
