I think there is a bit of a difference as well with those that bought plans based on a topo, and those that did eventually receive some guidance and supervision from a Ross associate (McGovern, Hatch, etc.) during construction. Even if Ross never made a site visit, the consistent quality of his courses indicates that the majority had some input from someone that knew what they were doing on site.
Now, if only the "mail-ins" maintained their layouts over the years with a stewardship that his fully on-site courses generally adhere to, he would be an even bigger GCA god. In New England there are so many Ross courses that they run the gamut from Salem CC with great Ross stewardship down to the public layouts that never had 75 years of member interest in Donald Ross. Many of these courses are so far from the original plans that Ross isn't even relevant other than a marketing angle.
I see the "mail-in" procedure in the teens, 20s, and 30s as a normal procedure then that is tough to reconcile now. We see it as a lack of effort today when it was just "the way" for many clubs back then, and often included support from one of Ross's underlings.
With these comments I believe I am on the side of Mr. Brad Tufts and Mr. Ed Oden.
To "mail it in" does not mean simply to put something in the mail, but rather to give only a half-hearted effort. I'll admit that to associate this expression with Ross's business practice of, in a number of cases, mailing out plans, is clever, but not particularly helpful.
During Ross's heyday (1919 – 1931) he operated as Donald Ross & Associates, including J.B. McGovern, Walter Hatch, and Walter Irving Johnson, Jr., with the latter two making substantial contributions to the finished design of "Ross courses." [By the way, as most of you know, most of Ross's own business records were destroyed shortly after his death, so we don't have a lot to go on. My information comes courtesy of Brad Klein's
Discovering Donald Ross, which owes a substantial debt, as do all Ross aficionados, to the late W. Pete Jones of Raleigh, N.C.] My understanding is that Hatch built lots of Ross's company's greens – what today we call "Ross greens." Maybe we should call them "Hatch greens"?
My point is that Ross had a business model that for his day was quite successful, to say the least, and has proven itself through lasting results. When I think of "Ross courses" it is with the understanding that a substantial number of them are what I would rather call "Ross & Associates courses," or "Ross golf architect company courses." Clearly, Ross did not personally visit all sites, but that in no way diminishes Ross's contributions to golf architecture or his status as a "golf course architect." In terms of the dedication of Ross to his customers, giving them good value for the money, you'd be hard pressed to convince me that he ever "mailed it in."
