Running Through a Legal Screen

[Junker]

Back to the original question. Saturday I worked a JV/V girls double header. In the JV game, first my parner called a visiting player for a push on a screen (no one told her it was coming), I called her for the same a few minutes later. At halftime her coach comes out and asks why we're calling that foul on her player. We explain that the screen is set legally and the defensive player needs to at least try to avoid the contact (my partner was a very experienced official and I don't have the specific wording he gave her). She gave us the "deer in the headlights look" and obviously didn't understand. First call in the 3rd quarter was a push on the same player. Coach says as I go over, "now I get what you guys were telling me." It only took 3 fouls.
