This will just get debated in a circle until an event dictates change. Unfortunately that event will be harm to a kid due to the safety risks associated. A lot of earlier posters noted that in the old U-9, U-11, U-13, U-15 days there were kids with a two year spread, so what is the big deal? When that was the case there were clubs doing U-11a and U-11b, etc. teams. Now it just concentrates into not being able to do single year 2020a and 2020b teams for example. Not enough coaches or fields. I think US lacrosse meant well to publish their gold stick best standards, U-10, U-11, U-12, etc. But the lacrosse industry just ignored it completely. So what if US lacrosse does name cards with birthdates? Unless clubs abide by US lacrosse guidelines and don't go off and self insure their events that does not mean squat. Unfortunately this is just going to eventually play out as an insurance issue. Just one kid seriously hurt, just one lawsuit and just one judgement/settlement paid by the insurers and this all changes to what this board is begging for. No way are the club guys going to accept liability again after something like that and those same guys are certainly not going to pay many multiples of their current insurance premiums if that comes to pass. Just my two cents. As a parent of two young kids, very frustrated as many of you are from a safety perspective more than a lacrosse one. Whatever happened to the best players craving to play up? Wayne Gretzky always noted that he never played against kids who were not several years older than him. Despite the safety risks he did it, and as important his parents were able to have the discretion do decide or not if he would be out there with bigger/older kids.
