I can't say you guys are wrong.I would think El Clasico is making 2 points: 1. You're not going to develop to international caliber via the USSDA and 2. Enough people recognize that fact now so if your kid is good enough, an agent or other rep on behalf of a club from outside the US will invite the kid to work with an overseas academy. I would agree with those points, if my interpretation is correct.
I'm just going to say that it's a much different experience to nurturing soccer talent in the US vs. Europe. I think the USSDA is taking the right steps to improve the level of soccer in the US, and build out the soccer culture in the US. But it's going to take a long time.
I read in the women's u23/u20/u17 World Cup thread how the Japanese girls were so much more technical and superior in short, precise, whole-team ball movement and passing. That didn't happen overnite, it's taken decades of work. In the beginning Japan just didn't have enough qualified coaches and instructors.
I think it's too early to expect the US to churn out a Pulisic every 5 years. Probably we need to train a few generations of players who will be better coaches and more of them than what we have now. Only then can we provide high quality training to a huge base of youth soccer players, and develop more Pulisic's.
