And my point is, your more "inclusive" model isn't necessarily a good model. The AAU/college basketball model could not be any more corrupt. Street agents, under-the-table payments, etc. Sadly, football is moving that way, with 7-v-7 camps and other venues designed solely for the benefit of the adults involved. Baseball, too.
Still, I agree with a good bit of what you say -- that soccer COULD be a lot more inclusive, and I think we MAY be moving that way with more and more fully subsidized Academy rosters.
I'd also say that, the 2-1 loss to Jamaica isn't the result of a poor player-development model, as much as the nature of the sport.
