It's only a matter of time that age requirements and rosters become mandatory for lacrosse - PAL, tournaments, etc. It is done in other sports and lacrosse is just lagging behind. With all the noise about holdbacks and cheating, this is the only way to address the problem. It's going to stink for the holdbacks when they have to start playing with kids a grade ahead but hopefully that will cause people to reconsider doing it in the first place.
