Matt,
I have enjoyed the discussions, too, but there is no need to repeat yourself again on your basic point. I understand it. And, if you haven't heard any reasons for it, then you haven't been reading my posts!
For example, you basically confirm what I said about clients not giving really specific instructions...how can they if they don't really know golf? Yeah, they get recommendations, or go on reputation, and some do go play the courses and go on gut feel of what they like best. But, none of that implies that they all hamstring their selected architects with detailed instructions.
If there is too much repetition for your tastes, its on the head of the gca's who may have hit their limits of creativity, settled in too narrowly on what constitutes good architecture, etc. On that we agree.
You make an interesting point that I was noodling on between visits to gca.com. Not only are gca's subject to certain points of view based on background, so are critics and golfers. Elsewhere there are comparisons to musical artists. I held up Paul Simon as an example of someone who changed his style. I always looked forward to new albums. Recently, I heard people waxing eloquently about Jessica Simpson doing a new style - Country Western. Since I am not a fan, I could care less.
As we alluded earlier, most gca fans would probably eagerly await a similar offering from their fave architect and decry one from from someone who they didn't like. (As in another Doak masterpiece vs another Fazio "mail it in." You confirm that by calling RTJ features "inane" thereby revealing your biases.
Is a Jessica Simpson CW album reinvention or is that marketing? What gca's have reinvented themselves mid career? (Actually, Mike Hurdzan quickly comes to mind, but after 30 or so upscale courses, is he starting to repeat himself like all the rest of us?) As to the inane RTJ features, they were very cutting edge when he did it early. They furthered the craft. But, no one feature or style works everywhere, or can accomplish everything.
And, we get bored seeing the same thing, no doubt. Is that a product of the TV generation, pop culture and a faster moving society where we always search out something new? And, if so, then why do we like going back to Scottish courses, or Golden Age courses that don't change much? It it because they are better, different, or because the nostaligia of "going back in time" touches us? I mean really, are all Ross courses that much different from each other? Mack at Royal Melbourne and Crystal Downs aren't that much different either.
Design differentiation has a lot of different levels. You are talking about over a career. What about at one place? When given a chance to design three resort courses in MN, I was very conscious of differentiating the designs, but are owners today more likely to demand the Bandon model - 4 courses by 4 gca's (if you count Doak channeling MacD as a 4th) vs. 5 by Ross at Pinehurst? As a Dye-Spann fan, would you have preferred the second course to be done by them or Doak at Black Mesa? Should Prairie Club have been done by CC, and if so, would they be required to do something completely different than Sand Hills?
Again, my point is that its just not so simple as saying that gca's have too big an ego, pander too much to clients, etc. Its a complex relationship bewteen artist, user and critic, with each playing a factor.
Disagree if you will. Your topic has certainly made me think, which is always a good thing!
So, what are you going as for Halloween? I think I will go as a struggling golf course architect again this year........
