One thing that has contributed to the loss in appeal in this area is when Legion Ball is competing against the clubs/accedemies associated in the metro areas. Kansas City has 6-8 of these type of orgs that can field 2-4 teams per age group in addition to local suburban teams that are taking more of the talent away from Legion Teams around metro areas.
Our team looked at the local legion route and it just didn't fit b/c of the talent level and when former players and curent ones are leaving its not a good sign. Of course there are exceptions like PG as stated and it depends on where your located.
Growing up Legion was where you wanted to be and if Legion is to evolve they need to play outside their leagues and tourneys.......I hope they do.
