Everything we do in life has ethical and non-ethical aspects to it. If you're driving your car and you're in a hurry and you force a slower driver off the road, should we say, "well, where were the cops?" That would be wrong! If you butt in line in front of another person at the deli counter , should you say, "well, the deli clerk could have said something". That would be wrong! We teach our children and hopefully a civil society fosters and cultivates ethical behavior.
Sports is no different. Fouling is a part of the game. Dirty, unethical play is not and if it arises, there should be strict consequences. Grabbing Paige's arm on the screen, making a full out swipe at the ball as Paige was driving to the basket by Carrington, flagrant foul, free throws and the ball and possible ejection.
Simple, straight-forward. Everyone knows the difference between dirty and a common foul. Good/great coaches also teach sportsmanship and respect for the game itself. Coaches that lack integrity struggle with that and when their players cross the line, they end up with "egg on their face". Notice I did not accuse her of teaching dirty play.
