Daryl - you made number of statements regarding SG's swing
That his right wrist was upcocked at the delivery position.
That he must have therefore have a 10-2-D grip - based on inference rather than based on observation.
That he was obliged to use angled hinging in the followthrough because of his right wrist hand positon at the delivery position.
Here is a swing video of Sergio Garcia's swing.
Here are capture images from that video.
Image 1 shows the end-takeaway - that doesn't look like a 10-2-D grip to me.
Image 2 doesn't show an upcocked right wrist - from my perspective.
Image 3 and 4 - shows the release swivel phase and how left wrist uncocking precedes release of PA#3.
Image 5 and 6 - shows horizontal hinging action in the followthrough.
Jeff.
