Well, it is pretty simple, 18-0 is uncalled for. Two touch, headers, and only scoring off crosses, still make a team better, and yet it protects the dignitty of the other team. The only way beating someone 18-0 helps your team, is possibly on PK's cause thats what it amounts to. No mercy rule, because thats just as degrading as losing 18-0. But scoring only on headers and having to do one and two touches can greatly help a teams ball skills. Possibly even get some nice footage for the college tape, you know, your daughter jumping up and heading it into the goal looks pretty good on film.
