I recommend the staggered stance drill for people that struggle with swinging too far outside-in.(This problem causes inconsistency in contact and leads to a loss of distance.) So by doing the staggered stance drill and dropping the trail foot back you are closing the shoulders more to the target which helps get the visual of the new swing path which is inside-out. This will help give you more consistency and distance by creating more depth in the backswing and allowing you to swing more in to out.
