Limit the number of foreign tennis players on womens teams
The NCAA needs a limit on foreign players in women's tennis. Why would you need more than two per team? When they forced colleges to provide equal opportunity to women in college sports, I'm pretty sure they meant American women or at least residents of the US.
If you want more American women to play tennis, make it worthwhile to spend the hours and money working on their game. There's got to be a scholarship available at the end.
There is no significant money made for schools by tennis. It is mostly by men's football or basketball. If you have to spend this money on women's tennis, at least make it American women.
