Whistling Straits
Years ago, I recall playing PGA West, where Dye had some bunkers well beyond the green, similar to WS above. My mentor went on and on about those not being necessary or a good idea. "Why would he put bunkers so far from the green where they never come into play?" Of course, my answer was, "Because they look Mahvelous?" (thank you Billy Crystal)
So, my take is that it is one of Dye's ways of pushing the envelope, being different from other '60's designers, raising the art, etc. as well as getting away from the dreaded formula design so many here decry. So, we can look at it now and in the future and see that the second row of bunkers, well behind the green, when Ross and a few others rarely used one bunker behind greens because they rarely come into play, as bad design.
I guess you don't get everything in any one design theory.
