The reality is, at the high school level, SOME teams:
1) Include inexperienced "athletes" to fill out sides and rosters;
2) Are coached/trained by well-intentioned, but inexperienced, less-competent folks; and
3) Are (occasionally inappropriately) supported by parents who know little about competitive sports, much less soccer.
Throw in shaky officials working crosstown rivalries, and you have a potential problem.
