I believe another reason is the fact that smaller towns have one high school in which all students go to. In the city all your talent is spread out between several schools. I have a kids club and I know goin in that I will produce some good kids (like Newbill) who will not attend Schlagle (the high school where I currently coach at) due to attendance areas etc...
Your record only means so much there is a sayin in wrestling that says "If you havn't been beaten you havn't left far enough away from home!!!"
