Klinsman is taking the same principles that are used in Germany,and pretty much everywhere else in the world when it comes to building a national soccer team, and applying them to building a USA team for international competition. My understanding, that in the past, there really hasn't been anyone that's been allowed to have as much control over the entire national program, literally from the U-8's to the senior national team, as well as Olympic program, as Klinsman's got now.
If it can get media support behind, and get $'s flowing, the rest of the world should be very concerned. A country the size of the USA, with as many athletes as we can produce, it's really only been a matter of getting organized, and time, before the USA becomes an international "football" player.
Remains to be seen if it happens, but the groundwork seems to be being laid down right now.
Remains to be seen how it goes in long term, and this was, as many pointed out just a friendly match, the qualifiers that matter are coming up, but we get another test against Brazil in May before that.
So far - arrow pointing up for USA soccer, big time.
