Garland:
For personal reasons I'd sub C&A for Alister, but am most intrigued by your Bill Diddel nomination. I was raised on a course renovated by him in 1955 and which has six all Diddel holes to this day, so I have a soft spot for him. Most would agree with your post modern PD nom, but I would take him off based on the number of his mentor's courses that he trashed in all or part.

It was suggested that RTJ be the modern architecture face on the mount. However, as the old saying goes anyone can make a golf course hard, it is much more difficult to make it interesting. Nix RTJ. William Hickman Diddel spent part of his career trying to make interesting golf courses without bunkers, i.e., anti-RTJ. He also invented a Cayman ball before there was a Cayman Islands golf course that needed a Cayman ball. And, he mentored the nominee for post modern face on the monument. Shouldn't a monument include an innovative mind if it is not Tom Doak's time yet?
... But with only a very small percentage of players able to play the greats and many courses closing due to lack of patronage - why can't architects create something short with no bunkers and a set of really cool greens for interest. Throw in some ditches for drainage and strategy as well.
...
Brett,
I give you Bill Diddel.
