Yes, I think we're pretty much on the same page; maybe a different paragraph. If I'm reading it correctly, without being negative, he sees a potential sacrifice for the kids who love (and benefit from) BOTH.

From a parental perspective, I'd say it's important for all to understand that Academy GUARANTEES nothing more than high-level training and competition. This may lead to an enhanced opportunity for:
1) That one-in-a-thousand shot at playing for a national team.
2) That one-in-hundreds shot of playing professionally.
3) That one-in-dozens shot of receiving SIGNIFICANT grant-in-aid support for college.
4) The better than even money shot at SOME aid for college.

Caveat emptor ... whether it be club, Academy, high school.
