Swing Down The Line

As a corollary to "square the clubface", many golfers will also agree that they need to "swing down the line" with the clubhead. Some others may feel like they need to "point" to where they want the ball to end up.

In the pictures that follow, it is evident that the clubhead is moving down, out and forward.



Why then the fixation on swinging down the line, focusing only on the forward component of the clubhead's downstroke orbit? How about the down and out?

To focus only on the forward portion of the clubhead's downstroke orbit is to commit golf's cardinal sin - the bending of the left wrist.
