I am on record in my belief that high school soccer is an important part of this journey, particularly for girls, and disagree with the DA's policy. Ironically, one of the pros of high school soccer for players, having their hard work and accomplishments recognized within the community (like NLI day), has been ridiculed by more than one US Soccer leader as not important.
That being said, I would expect more from the adults in the school district, and do not support them holding the children accountable for the actions of their parents, if that was a factor.
Whether you are able to play or not, your school team is always your team, and kids should endeavor to be a part of it in any way they can, even if the DA says they cannot train and play games. Just as I believe kids should travel and attend their teams games and practices even when they are injured (unless they are rehabbing, unable, or cost is prohibitive), if my child was prevented from playing HS soccer by the DA, I would still expect them to try to be part of the team.
Perhaps that is one policy we should all consider as a response to this unfortunate circumstance.
