AAU basketball is the only youth sport that has the best of the best play each other. But youth football has 3 strong leagues that never play national together. Soccer I have no idea because I am not from Spain or France. I think youth baseball has 3 or more large league names to keep all the teams apart. Youth softball lets there teams play in all three of there major leagues. But you have to lose and gain players becasue of the age rules. Just saying its the same everywhere I am guessing from my veiw point
