Why is it that YJ can have 5 teams in this age group yet parents will turn other clubs 2nd teams? [/quote]

I guess because they look at yellow jackets as the only A team on Long Island. The rest are B+, B, and C teams. Maybe they have friends on the team. Maybe they feel they will move up if their daughter improves, which does happen more than you think. A lot can happen between 7th and 10th grade physically. That's why the whole jump from team to team is not worth it unless your daughter was slighted or had a bad experience.
