Mostly due to competition from the firmly entrenched American sports of baseball and football, which cover fall to winter, and spring through summer.
There isn't much space in between the two and the other American sport of basketball tends to pick up most of the slack.
The interesting thing is most kids in the suburbs play soccer, not football in the fall although baseball is the most common team sport played in the summer. This probably has more to do with the amount of equipment required for football as well as a designated field with goal posts and yardage markings and the contact nature of football more than anything else though.
