Adam,
I think Tom hit the nail on the head, with a great site, it is probably harder to produce an awful golf course than create something special. The real gift lies in designing a course that evokes the essence of the site, and lies in harmony with the natural landscape. Sand Hills is truly a great site, and it would be difficult to build a bad golf course there, however, in terms of architecture, it would be quite easy to design a mediocre golf course that most people would love because of the setting. Coore & Crenshaw, being the talented and visionary architects they are took a site that would be a 5 on the Doak scale without a golf course, and turned it into near perfection.
