Golf as a three lane highway, the pivot, the arms, the hands.

Looking back at some of the clips of Nicklaus in his prime and at Moe Norman, I got to thinking about what that 'three lane' highway could mean.

Consider for a moment, a 2-D view from above the golfer.

Moe Norman is known for saying "my club never goes out of bounds", and by that I think he means he had a 'narrow lane'.

Imagine that 2-D view from above, a dot representing the sweet spot at address, another the hands (PP#1).

By a 'narrow' lane, what I am saying is that the distance from the sweetspot at address, and the sweetspot at the top/end, is more narrow for an accurate player.

That doesn't require a steep plane per se, but certainly shows why a steeper plane can be considered more accurate.

Take a look at Kenny Perry's motion from this 2-d, above the golfer perspective. He keeps the club very much in front of him. The sweet spot never gets behing PP#1 when viewed from above (or does so much, much less than others).

Same is true for Furyk.

That distance between the sweet spot at address and top is a 'narrow lane'.

Nicklaus is perhaps one of the best examples.
