Old thread, but I just stumbled across it and feel I must respond.
First, courses don't "fall from grace" because they don't advertise in Golf Digest. There is a strict absolute separation of church and state at Golf Digest. Advertising and editorial are completely separate. Golf Digest's rankings, which I've coordinated since 1985, has never been influenced by advertisers, amount of advertising (or lack thereof) or anything like that. In fact, most courses on the 100 Greatest are private, and dont' advertise anywhere.
Second, some define "fall from grace" as a slip within the 100 Greatest. Even if it ends up at No. 100, as Atlantic is this year, it's still one of the elite 100 in a nation of 16,000 courses. Some disgrace, eh?
Others consider it a "fall from grace" if the course drops off the list. It irritates me sometimes that we in the magazine business (not just golf magazines, but magazines in general) have created this "list" mentality whereby, if a golf course (or restaurant or movie or movie star or whatever) isn't among the op 10 (or Top 25 or Top 100), it's not worth anything. Gosh, a course was once on the 100 Greatest but isn't any longer. Big disgrace? Hardly. Still worth playing, especially if it just happens to be one that's been overlooked or forgotten in recent years.
With Golf Digest's rankings, it takes a minimum of 30 evaluations to qualify for the list. We retain the evaluations for 10 years, and supplement them. But 10 years (3 surveys) later, evaluations start to expire. Sometimes we don't receive enough supplemental evaluations and some courses slip in the ratings or drop out completely. As Darryl Boe pointed out, with so many courses tightly bunched in our numerical scoring system, a dip of an eighth of a point in each of the categories can mean the difference between a Top 40 ranking and completely off the list.
How can a course drop 40 spots in one two year period? By slipping 20 spots and having 20 courses overtake it. Not that hard with so many courses competing.
But, ultimately, what happens to certain courses is the simple fact that tastes change. In the early 1980s, the Nicklaus "conehead mound" architectural style was all the rage for a while. Loxahatchee and Grand Cypress made our 100 Greatest. By the end of the decade, it fell out of style, as reflected by our panelists evaluations. Six years ago, Mike Strantz's stuff was all the rage. Royal New Kent made our 100 Greatest. Now there's been some backlash about his architecture (including some on this web site) and he's not as hot as he was. Royal New Kent dropped off the list, more as a result of lousy conditioning than anything else.
Oh yeah, even before the era of magazine lists, architectural styles were in and out of fashion. People never thought twice about planting the hell out of Donald Ross' open landscapes. Tillinghast was so forgotten that when Frank Hannigan wrote his 1974 piece on him, it was the first mention of him in print in decades.
As far as I'm concerned, if any course has undergone the scrutiny that Golf Digest places upon golf courses and succeeds in making the 100 Greatest, even for one brief two year period, it's a badge of honor that I'll always respect. Even if others think it has fallen from grace.
