Some of the videos of Hogans swing that were introduced in this thread show a very conspicuous shoulder turn and Right Forearm synchronized rotation through Impact and Follow-through.
Let's not forget that Ben's typical shot was a Fade. He got that Fade by tracing an Open Plane Line, i.e., a Plane Line aimed left of the target.
Normally, the Stance Line is parallel to the selected Plane Line (1-L #19). But Ben often stood Square or even Closed to the Target Line (and thus well to the right of his Open Plane Line). He did this to promote an unrestricted Backstroke (10-12-B).
I'm not relying on hearsay. Nor am I being fooled by misplaced camera angles. I've stood behind the man on the practice tee at Augusta National and watched him hit Fade after Fade from a Closed Stance.
Most observers saw the obvious: he was "swinging left" of the Target -- a motion made even more apparent because of his Stance Line. What they didn't see was that he was deliberately Tracing an Open Plane Line.
