Once upon a time there was a “Play Your Kids” movement. FC Dallas was the main benefactor of the meme-ification of soccer organizational strategy. They did in fact play their kids and a few dozen writers and podcasters got very excited. The fans got about $12 off their season tickets when those kids were sold to much better teams — teams that try to win.
And then the Seattle Sounders played their kids and the meme was tired and the Seattle Sounders didn’t really get that attention from the few dozen podcasters and bloggers, because the Sounders were winning, and that’s not really the point of the meme.
