Every coach may have their own opinion. So if your looking for what a college wants. Study that school and that coaches philosophy. For me I teach the girls to pivot and point their toes towards first, and the right foot steps towards first and lands at the same time the bat "catches" the ball. This is for a sneaky drag bunt. For a sacrifice, they will square up early and slowly exit the box after contact to box out the catcher for a half second. Gotta be subtle on this move so you dont get an obstruction call.
