Fun Fact: There are more American soccer players than any other country in the world. Basically, we all played AYSO or some other form of youth soccer. America's passion for soccer is damn near growing faster than our institutions can handle it. I spent 2 years wandering these states and never failed to find a pick-up game in any city I stopped, regardless of size. The way the MLS is expanding will force us to implement promotion and relegation in the next decade. That statement is not necessarily true, we do have an affinity for creating our own amalgamations of other nations structures, but with Klinsmann at the wheel I don't think the MLS' development will go any other way. And thats the other thing, Klinsmann is at the wheel. Klinsmann operates under the pressure of his ideologies in the same manner Wenger does (or so it appears to me), but from a German perspective.
I think you're wrong, and I don't just say that to be a thorn in your side. Arguably as well I may be overly optimistic, but there are a few things obvious to me about the future of American football which I think may change your mind.
-The passion for football in America is growing faster now than it ever has an may ever will again, the previous decade was crazy and the next will be incomparable.
-The American soccer culture is different than any other soccer culture in the world in a very important developmental way. It isn't established. And it is ripe to be molded. And if the appoint of an ideological nutter like Klinsmann along with the innovations such as how player transfer value is determined or "vanishing spray" doesn't show the exponential difference in the developmental path ahead of us. I'm not sure what does.
(I am now desperately tired apologies)
I think Klinsmann is the real kicker here. His appointment and subsequent backing truly shows the intentions of the people driving this ship. Soccer, football whatever, it earned the title of "The Beautiful Game" after finding a philosophical style of play to grow from while never altering it's uncompromisingly simple roots. And if we can keep people at the helm (for long enough) willing to sacrifice superficial achievements to develop the core principles that define what is referred to as "The Beautiful Game" in this budding culture, our money, population and American bullheadedness will get us the rest of the way within a generation. 20-30 years we will be the powerhouse you see in every other sport if not much sooner. And we will get there on a wave ideology in a ocean of crassness. The End.
