I see no problem with the list -- mass circulation golf magazines need to run provocative stories to get people talking, and as long as they are not factually dishonest, they can be kind of fun.
And it seems to have been successful at starting a conversation here, so I'll join in: In my opinion, the holes at Sand Hills do NOT all look alike. I haven't been there in several years, but most of them still stand out quite distinctly in my mind. There are uphill and downhill tee shots and approaches, elevated greens, two-tiered greens, exposed greens, protected greens, straightaway holes, doglegs left and right, long and short par 4s, reachable and unreachable par 5's, etc. I really don't know how much more diversity you could fit onto a course situated in the middle of arid nowhere.
And I think that's why some may sense a sameness. It's not that the holes are similar; it's that everywhere you look other than the holes, the surrounding scenery is the same: rolling, rugged, ungreen sandhills.
Put an ocean, a river, a lake, a forest, a mountain or even some condos around the extrerior of the course, and the impression one would get looking around from each teebox would be quite different. As it is, the golf holes provide the visual interest. At least, they did for me.
