David,
I haven't played enough C and C to be an expert, but what I meant is a little of all of what you wrote.
Stylistically, for sure, (honestly, a lot of my thoughts are based on pics only). I have heard and read that many of their green complexes can be repetitive (Lion's mouth etc). I have more experience with Doak, and I don't find his work to be repetitive at all. For what its worth, I prefer C and C's style much more than Fazio.
I haven't noted a similarity in greens, except perhaps in how they are constructed. There are definitely some repeated themes, but I'd have to see more to really believe they were too similar.
Fazio has built a ton of golf courses, and for sure, he copies a lot of what he had done in the past. C and C have built very few, so it is easier to not do rote holes as you say.
Maybe, but I think the fact that C and C usually committed to what the ground gives them pretty much eliminates the possibility of out and out copying of holes.
I think part of it is that Faz often builds on difficult sites, and has found holes that work on difficult terrain, and he goes back to the well on those, perhaps too much. He does too many false fronts for my preference, and not enough centerline hazards.
Not even experience on his courses to comment.
Fazio gets blamed too much, imo, for defacing our classic courses. I blame the people that hire him to make changes more than him. When Coore touches an epic green like Prairie Dunes number 2, he gets a pass. Fazio goes anything and gets killed.....
Well, I am not so sure that this is true. It seems like there is a spectrum of reasons one might condemn a designer who alters old great courses. Here are just two:
On the one hand, we could take the near absolute position that the great classics should never be altered by anyone, except in extreme and absolutely necessary circumstances (think eminent domain.) Under this view, Fazio and C&C are equally culpable.
On the other hand, one could recognize that sometimes changes are needed and may actually be for the best of the club/course, but only if the changes are carried out in a way that is entirely sympathetic and consistent with the style and personality of the course. Under this view, we might look at the reasonableness of and need for the changes, as well as the final result to see if the changes fit in with the course and make sense.
While, I have not yet seen the changed 2nd at Prairie Dunes, but I have seen some of Fazio's changes at Riviera. I am not sure the reason for the changes, but whatever the reason, some of them completely clash with the rest of the course. For example, the extension of the 17th green in the back right is absolutely hideous and looks nothing like anything on the course. And it has a little mound surrounding it that I do not get at all.
