US lacrosse just adopted a new player segmentation policy for player safety. They are promoting players play within a 12 month age range with an age cutoff of September 1.

"Age is based on player's age as of September 1 in an attempt to align with the majority of school systems nationwide to allow players to play with people in their own grade level."

WSYL will have to comply next year for the safety of the kids. This year I guess will just be a free for all with a mix of ages and grades. Too bad for the kids it turned out to be such a mess this year.
