It should be grade based with a cutoff and roster like football. But it still doesnt matter because the rules will NEVER BE ENFORCED. The leagues and tournament bodies that make the rules blindly look away while taking the money. Club X enters 5 teams in each of your tournaments are you really going to complain? Team Y says if they dont bring in older/out of town/ringer kids then they cant field a team and hence cant pay you... who can turn away a check i mean player?
