You guys are missing a huge...HUGE...thing as to why Soccer is never going to be a thought in the US
Let me give you a visual:
Footall: Pee-wee > High school > college > pros
Basketball: Youth > High school/AAU > college > pros
Baseball: Little league > High school > college/minors > minors > pros
Soccer: Youth > High school > pros (maybe in the US)
There is honestly a shitload of youth soccer leagues. As many as any other sport. There's a slew of high schools that support their soccer teams. But...it's the leap from high school to college which is greatly missed in the US!
We love our college sports. We love college football. We adore the tourney in college basketball. And baseball...it's so elaborate that if you don't watch college ball, you probably have a great chance of catching and tracking the player from class A to the pros.
Kids want to be famous in the sport they play, hence why many play it. With soccer...you can get famous, but not here. You gotta go outside the US.
Now, will soccer ever be popular here? NOPE. No strong college connection. Title IX helped ruin a possibility..but it wouldn't have happened if mens programs didn't get cut out. No minor leagues. Nobody will care to bring their family to the fields and watch the minors while enjoying a cold beer because it wouldn't be appealing.
And of course, MLS is so lackluster that it can't even get a decent TV deal. Yea, some cities have good attendence...but nobody knows who the

is on the field because there's no college backing AND no minor leagues to follow!
I'm just saying....the key to success in team sports is college. Hence why hockey is always so far down on the ratings poll too and why lacrosse is seemingly a regional sport. If we Americans can't follow you somehow from youth to the pros...we ain't going to care about you!
*Of course, all bets are off when it comes to individual sports, a la nascar, golf, tennis...
