One thing that can be added is, whether or not your son plays on one of those four teams, it doesn't determine how good your son is. Those four teams play great team lacrosse but there are individuals on other teams that may be better. Give your kid the strength to remain on a team that may not be the top 4 if you think they are getting the most out of the program.

There is something to be said about being 1 tier below. Your son gets to play against better competition which will make him better. If your son is really good then he has an opportunity to be a leader.
