You cannot be serious about that there is no difference between grade based/age based. Every other sport is based on age. A certain organization who shall remain nameless (cough ... Crabs) fielded a handful of 8th graders in the 2016 HOCO league that would turn 16 in the fall of their Freshman year and one who was 16 in the 8th grade (March birthdate). Grade based is a joke. The only people defending it are the people who game the system.
