Greg,
I think that Tiger Woods has steepened his shoulder turn simply because he is more bent-over at hip level at address. Some golfers prefer that greater degree of increased spinal bend inclination (eg. Matt Kuchar and Keegan Bradley and Hardy OPS golfers), but that particular change cannot singularly explain his greater degree of driving accuracy.

I also think that shoulder turn with less #3 roll in the backswing has helped him keep the club more in front of him. Why do YOU think he is driving the ball so much better than the last half decade?

I agree.
I don't know why Tiger is driving more accurately. I would be interested in reading/studying/analyzing any rational suggestion. However, I don't believe in the validity of BM's claim that the cause of his increased accuracy is due to a greater amount of "bobbing up-and-down" motion. How could that increase accuracy?
Jeff.

He has always bobbed up and down so that in of itself would not do anything more for him than say 2009, but part of the connection I thought BM was making was related to the hand path. I would need better evidence in order to study the hand path and its affect on the club head in Tiger's swing in order to come to a conclusion.

I would agree that if BM is implying that Tiger's improved driving accuracy is due to a changed hand arc path that he has not presented any detail to support such a claim. I think that he is basically propagating his standard biased opinion about the nature of the "forces" in play in phase 2 and phase 3 of the downswing and his "belief" regarding its "effect" on the hand arc path - and I reject the legitimacy of those "forces" as having an "effect" in terms of altering the hand arc path.

nmg,
Why does Tiger Wood have to "bob up-and-down" to that degree in recent years to get his hands to follow an optimal hand arc path?
What was wrong with Tiger Woods' hand arc path in his Nike commercial swing - when he didn't "bob up-and-down"?
Jeff.

A squat action is consistent with a golfer's ability to generate a contracting spiral hand arc path, but it doesn't necessarily cause it to happen - because the humeral heads can move independently within the two shoulder sockets while the upper torso rotates around a constant spine angle and constant head/upper swing center position => and thereby generate a contracting spiral hand arc path of variable shape. The shape of the hand arc path is primarily dependent on the relative position of the left shoulder socket at every moment of the downswing combined with the variable pattern of 3-D movement of the left humeral head within the left shoulder socket - although it can be secondarily affected by a vertical movement of the left shoulder socket in 3-D space due to a concomitant "bobbing up-and-down" motion of the upper swing center. However, a golfer doesn't have to bob up-and-down to generate a "contracting spiral hand arc path" of optimum shape.
