If this were a traditional American league people would be using the term dynasty. I guess that they all emerged and merged at the same time. So it won't be over after this group it will only change. As you know the American Youth Soccer Association is reported to have 1,200,000 kids registered with the American Youth Soccer Organization having well over 600,000 registered youths that's really amazing. Now without insulting our other colleagues in those other sports, I'd have to state that there is a significant difference between, bowling, shooting and soccer.
Soccer is by far the largest participatory sport in the country no question about it.
