When other club sports like soccer are strict on this why is pointing this discrepancy in lacrosse nonsense. I've seen well talented kids kicked off their club team when a kid plays down takes their place. And parents who brag that their kids are playing up in club when actually playing in the right age group, not school year, are right to be called out.
Fighting a losing battle. The holdbacks won. If you can, reclass. Do it . You will competing more and more with players getting an age advantage most dont get.
