I had only seen a shorter clip of that interview. Very interesting, this is something I am dealing with in my swing too, I think. That is about where the similarity between my golf and Tigers ends. Im getting just a little arched and slightly laid off at top. Its small but its there. Its an unwanted horizontal motion in the left wrist which disturbs the plane of the Left Hand Wrist Cock. For me, it makes left wrist cocking a little harder and promotes a sweep release.
Arched at impact is a nice bit of insurance against throwaway. But the Left Wrist cock and uncock is vertical only motion, like hammering, no horizontal motion. Hogan clearly stated in Five Lessons, that the left wrist begins to supinate near impact. Hogan, actually had a little Horizontal motion himself but the other way around, getting a little cupped at Top, a wide open clubface for hook prevention purposes.
Tigers clubface would be more closed at Top if not for his extremely weak left hand grip. Yoda could fix all this for Tiger over a coffee in the Grill Room, Im thinking.
Do you think Hanks parallel planes or right wrist cock and uncock theory could be a contributing factor for Tiger?
