This is getting old guys - enough already
if a kid is in the sixth grade and he is scheduled to graduate in June 2018 then he belongs on a 2018 team regardless if he was born in 1998, 1999 or 2,000 so just stop it.

in the past some kids that have been on a grade based team were not eligible to play in age based tournaments (a lot of kids have missed playing in the U15 nationals with their team because although they were legitimately in 9th grade they were born in Oct,Nov or Dec) US lacrosse addressed this when they moved the cut off to 8/31 and now most but not all kids in 9th grade will be eligible.

I also don't buy into the safety issue - our 2018 kids will all be playing middle school next year and the heights will be from 4' 6" to 6' and the weights will vary from 75 lbs to almost 200 lbs and those will mostly all be 2018 kids born in fall 1999 or 2000 so lets all deal with it and get back to talking about how much the other teams suck and not about how old they are or what grade they really should be in.
just my thoughts
