The ODG's ( I LOVE that term, I really do! ) have two huge advantages over the YLG (hate that term.) The first is the sites. The ODG's had far greater choice of sites. Macdonald spent several years traveling between Boston nd DC before settling on Southampton. I have no doubt that part of the ODG's assignment was to help clubs choose among various optional locations to build a course, whereas today, the site is probably a given. So to the extent that you can't have a great course without a great site...the ODG's have a huge edge.
Secondly, many of the ODG's were hired by the wealthiest people, and those clubs remained strong over time, with plenty of resources to create and maintain near-perfect playing conditions. When people rave about Augusta, it is not just the course design, it also includes the fabulous greens and meticulous manicuring. That is true of almost all of the top old courses.
The current architects probably know 1000% more about HOW to build a quality course, how to make the course drain, how to make the grass grow best, how to build greens that will putt well and withstand traffic, etc, etc.
So, IMO, if we could send today's best architects back one hundred years in time and give them their choice of sites, they'd build BETTER courses than the ODG's (did I mention that I like that term? )
Bill, what classification would you give the sites that the Bandon courses, Sand Hills, Ballyneal, Chambers Bay, Sebonack, Bulls Bay, Arcadia Bluffs, Kinglsey, Kinloch, Erin Hills, Hidden Creek, Tallgrass, Rustic Canyon, Cuscowilla, Tobacco Road, Whistling Straits, Chechessee, Friars Head, Inniscrone, Kapalua, Lost Dunes, Rock Creek, etc, occupy, compared to what the golden age architects had to work with?
How would you compare the men who hired the golden age arch's vs say, Mike Keiser, Herb Kohler, the O'Neals, Dick Youngscap, Mark Parsinen, Michael Pascucci?
As for knowing 1000% more about grass, drainage etc., I'm not so sure. More technology at their disposal? Sure.
It seems to me that today's architects have built great courses on the sites they have been given. Fazio states that he prefers having a flat, featureless site. But the premise that today's architects could go back in time and build better courses on the same sites as CPC, NGLA, Maidstone GCGC, Pasa, Valley Club, etc is bit presumptous. They would have the advantage of knwoing what someone else had built there at one time, and "go from there".
