no offense, but you say some weird crap.....
Well, based on your previous posts, I can tell you are pretty legalistic (not meant as an insult), so I am assuming the phrase that struck you as the most weird would be "the out of bounds line is just a formality".
There are two philosophies to refereeing. You can either view yourself as the defender of the LOTG, or as the peacekeeper. The defender of the LOTG does the game of "Soccer" justice. He follows all the rules, even if both teams are not aware of one particular law, the referee does not care, he enforces them. This is a good refereeing philosophy for most games, especially the competitive games that determine futures.
Then there is the refereeing as a peacekeeper. What you do in this style is you imagine that the two teams are just having a scrimmage or pick up game with each other without a referee. You then call whatever both teams think need to be called and are there in case the teams cannot agree on what the result should be.
For example, two unskilled girls are running side by side, there is fair contact and one girl falls down and sprains her wrist because she doesn't know how to fall properly. Under the LOTG, this is not a foul. However, everyone on the injured girls team think it is a foul, what's more, the girl that bumped her down thinks it was a foul and her whole team thinks she committed a foul. You are now in a situation where everyone on the pitch except you thinks there was a foul.
At that point, you should just call the foul and betray the game of soccer because it is clear that the parents and teams want to play something, but that something is not soccer. This strategy is best for the uLittles and the Adult League games (for opposite reasons of course).
My point is that most uLittle games are just organized pick up games. I have played a lot of pick up soccer where you call your own fouls and you only do a throw in if the ball went significantly past the boundary line. No one cares or has the patience to call out of bounds when it is out for a half second, we just want to keep playing. Whether the ball was 6 inches to one side of a line or the other means very little, because the line is just an arbitrary boundary that exists just to add a little order so we aren't dribbling through the bushes.
It is like the 25mph speed limit. It is just a line in the sand. If you go 26mph, it doesn't mean you are all of a sudden immoral and endangering neighborhoods. In the same reasoning just because a 16 or 96 year old is driving 16mph in a 25 zone is not inherently less dangerous to neighborhoods.
