Those couple of months... if LI kids were just 3 months older boy would it make a difference. Silly. Smaller, slower and not as aggressive. Have them play some football , hoops or even hockey. They are behind athletically and 3 months will not change it. Older ages have a wider skill level separation. No longer the case.
The point isn’t about my kid. The point is about your kid. If he played in the 2025 bracket, which he would if he lived on LI, he would be smaller and slower. Just stating the facts.
