Also, it shouldn’t be up to a coach to ‘challenge’ the roster of whoever his team is playing against. The kids should have to send proof of age to the governing body of the sport, get verified, and receive some sort of proof back that then either lives online or goes with them to every game the play - just like soccer and hockey. The concept of roster fudging and illegal guest players and even holdbacks in general is just not a thing for any other sport. Don’t put the onus on the coaches to challenge and enforce the rules.
I agree with most of what you say above but make no mistake basketball has similar issues with holdbacks in travel leagues with loose enforcement. Granted not a contact support so some of safety issues are lessened but to say lacrosse is alone on not enforcing roster/age limits is a reach.
