Not sure what the relevance of talking about the NFL is.
Out of about 85 girls that played on 2012 teams, there are 59 committments showing. Of those, 47 are D1. Just setting the record straight.

Regarding the 700 girls: no question that some are weeker than others, hence the concept of leveled teams. No question that CR is heavily motivated by money. That said, are you suggesting that those weaker girls should be turned away? Not everyone does travel lax with hopes of playing in college. Some simply enjoy playing and want to elevate their game. This can't be done through a town team at the younger levels and even at the older levels, some schools are very weak. Some of those weaker players may end up on a YJ "D" team. Some may play on a TG "B" team. Why would you think that they shouldn't try to better themselves and play a game they like? If other clubs were more viable, they would attract more girls. End of story.
