Do you really think the YJ are the only kids who end up playing at good schools? They are not. Sure the YJ list is impressive and they are a great club, and they also have 3 or 4 teams per grade. More players, more players playing in college.

http://www.libertylax.com/alumni/ this is a list for the Liberty, a smaller club than the Yellow Jackets but many of the girls will be playing on the same teams. I am sure the same could be said for girls on the Express or other clubs.
