Tom -
You could add MacK to your list of wacko's. He did some in-yo-face, nutty stuff. People made fun of "MacKenzie greens". ANGC when it opened looked like it was designed by an architect on acid. It was Fear and Loathing in Augusta. Wild, daring stuff that he might not have gotten away with without a Bobby Jones there to support him.
(It will always be a mark against MacK, however, that he didn't die younger. A bit of bad form, that.
)
That wildness is missing from so much modern stuff. Maybe it has to do with the fact that so many people these days do architecture in order to put food on the table.
Even the very best moderns don't take the design chances that MacK, Leeds, H. Wilson, MacD, Thomas and others took.
Why? I have a pet theory. Take it out to the backyard and shoot it if you want, but it goes like this:
Might the prevalence of water on modern courses make a difference? Instead of building difficulty into the design, you import it by way of water hazards. Which soaks up the quota of danger allowed to a course, requiring that the rest of the design be more vanilla?
I think the rarity of water hazards back then and the abundance of water hazards now makes a difference in how you approach the design. The amount of difficulty you can build into the dry part of the course is capped by the extreme danger posed by water at other locations on the course. Water hazards soak up, as it were, the quota of acceptable difficulty and leave an architect with fewer design options at other places. If you did otherwise, the course's slope would get too high.
Imagine, say, PII with six or seven holes with water in play. I think Ross would have had to balance the extreme danger posed by those hazards by softening other parts of the course. Resulting in a far less interesting course.
