You can play the ball OUTSIDE your front foot--IF your first move after turning back is a strong weight shift to your front leg "post." You can hit it straight because you can bring the clubhead from inside the target line.

However, even if you play the ball in the middle of your stance, if you lag back and swing around your back foot-- the clubhead will slice across the back of the ball--imparting slice spin, and you will slice it across two fairways.

Bottom line, the golf swing is turn, PLANT (the front foot), and then swing.
