Last I knew, NCAA's allows H.S. and college players to keep $10K in prize money plus expenses per year. There's also a number of programs that help players in the fall season play a few futures and challengers. We've even seen a few players at marquis programs play a pro tourney in the spring in the middle of the dual season. Guessing the player negotiated that with the coach before committing.When a 15-16 year old junior wins first few hundred bucks in M15 or M25, he (she) won't let it go. The experience of that is like an addictive drug. It's so important to make sure such kids don't start flying high in the sky with their dreams. The road to future sure should have more options at this vulnerable time. What is tough for those kids is the education and support that sponsors could provide a bit better than they have with some young players who'd like to be more independent than hooked up on an academy or a coach.
There are some coaches who preach pro or bust mentality, and if the player has to go to college they couldn't hack going pro at 17 or 18. I mostly see it from internationals, have seen an example of that here in the states. Whole other story. That's hog wash. There's a number of internationals and Americans in the top 100 who played college first.
