All are US Lacrosse eligible. You are wrong, but pretty persistent in your argument. Just accept that your team lost to a better team for once and stop looking for excuses as always. Is this what you teach your son? Look for an excuse every time something adverse happens? Also, STEPS is not the first 2017 team I have seen with "big kids", maybe we grow them bigger in NJ, but I guarantee all are US Lacrosse rules eligible. End of story.
