TEPaul,
If you'll look at the spacial relationships of all of the deep bunkers at NGLA to their adjacent greens, # 13, prior to this project, stands out like a sore thumb, due to its offset nature.
I can't think of anywhere at NGLA where a deep, greenside bunker is so detached from the green.
While that's no guarantee that the green originally abutted the deep right side bunker, surely it presents a prudent statistical argument.
George Bahto,
If you recall, one of the tees on # 2 is merely an extension of the green.
In addition, # 5 tee, # 13 tee, # 14 tee, # 15 tee and # 18 tee are in harms way as well, so a tee to the left rear of # 12 green would enhance the angle of attack relative to the juxtaposition of the bunkering around # 13 green.
The next time I visit, I'll make a point of standing over there, not far from the new back tee on # 7
