The problem with soccer in the U.S. is many kids don't learn the game of soccer.
Many kids learn that soccer is about running and shooting and not passing just being selfish with the ball.
I've watched grade school and high school games for 12 years now. You get the parents on the sidelines yelling "Boot it" "just kick it"
Many kids can't pass a soccer ball to their teammates feet. They pass the ball and the teammate has to run to get it.
Youth soccer in the U.S. is pretty sad.
