The 3/4 guy keeps saying that 3/4 are age appropriate. No matter how many times he says it or insults people that point out he is wrong, he is still wrong. My 2017 was born in October 1999 and is on a top club team and played varsity this year so yes, he played with and against older kids. I think the point is with these teams such as Under Armour is that the boys who are two years older should be embarrassed to be on a 2017 team when they are 17 or 16. 5 years old. Play with your age. Pretty simple concept unless you can't hang with your age on the filed.
