1. The 18th green already borders the OB right. If they moved it further right they'd have to find a pin positions in one of the shops in town.
2. The VofS will never be moved right even if only because that would spoil the view of the green at the Opens for the members of the R&A.
3. The VofS is not at all over-rated, because the course plays fast and firm, and trying to stop a half-wedge to a pin position a few yards from the edge of that "depression" requires significant skill and nerve.
If CBM had the proper vision, nerves and soil condidtions, he might have tried to replicate the hole and the feature at NGLA, but he didn't. I ocasionally wonder in which if not all of these he was found lacking?
