My son is not a holdback. He is a 2020 who meets the us lacrosse guidelines for u13. I am comfortable with him playing against older 2020 kids who may be older so I am fine with him playing in the aa division. If I wasn't I would have signed him up for another team that played at a lower level. When your son tries out for a club they tell you what types of tournaments you are going to and the types of opponents they will play. If you don't like the answer pick a different club instead of whining.

The idea that you can't figure out in advance what types of opponents you are going to face is silly.
