I agree with all of the points that it is tainted to stage kids so they can play down and dominate. My question to the other posters is,

With that as a given, why are college lacrosse coaches so smitten with it? Just me asking, but is there something more they see here than a 15 year old blowing up smaller 13 year olds in 8th grade? Most 15 year olds who are decent athletes will dominate younger and smaller kids, not just in lacrosse but in every sport I've had kids in. This recruiting angle seems really strange to me.
