I agree with you regarding specialized sports that are not “pickup” game in nature like lacrosse.
But this whole “specialized” teams are typical new age crap.
You have latin 3rd worlders who play in rags and lousy equipment that end up kicking butt in the majors. Why? Desire and lots of playing.
Same with basketball. Do you think black kids in the cities became great because of travel teams or clinics? No way, tons of “playing” and then if one is hungry, individual practice.
