By rule how? Fouls are not to be called unless there is displacement or some advantage is gained. They did not throw out all the other rules for foul calling because there is a description of a hand check. I only call a foul when the Rhythm, Speed, Balance, or Quickness is changed by the contact. If they play through it I let it go. At that level it is not difficult to have those things changed as I am sure the girls can barely stand and chew gum without falling down. Stop worrying about what an 8th Grade coach thinks anyway.
