US Lacrosse states; U14: All players must be 13years old or younger on the August 31st preceding competition.
The reason that US Lacrosse uses the "U" groupings is to avoid any discrepancies as far as age, this is done to keep the players SAFE.
"Cheating" only exists when teams have players that "CLAIM" to be graduates of a graduate year when the player should in fact be graduating a year or sometimes if two before that year. Why can no one get the concept that just because "Johnny" is actually graduating in say.....2019 that does NOT mean they are the appropriate age for that graduating year!?
So as far as the argument here goes, even if the player in question is a 2018 graduate it IS possible that he can be the SAME age or even YOUNGER than some of the players that are graduating in 2019.
