ML dad again. I don't care about holdbacks because my son is on age as defined by the public schoolers. I have been through this before because I have older kids as well and have gone through this in HS already. Importantly, nor do I live vicariously through my kids' lacrosse play...so whatever. If "they" (define "they" for me please) change the rules then everybody moves up or stays and it will all shake out. Once the kids hit HS if you still care about holdbacks you are going to be one very sadsack dad.
