The article indicated that interest in soccer among kids in New Jersey isn't declining -- they're just migrating to private training programs and traveling club teams instead of playing in high school.
Soccer and some other sports have a very well developed league outside of schools. I’m not aware of those for Football in particular. Most sports are developing them as concentrating on one sport and making it a year round deal becomes more prominent. I think it will be hard for that to happen in Football because of the huge personnel needs.
