Mike,
I have played many of C&C's courses and frankly like all of them. In fact, I can't think of one that is less then very good. However, if you see a lot of them, they do tend to start to look the same in many ways. That is not necessarily a knock, just an observation. I have played Chechessee and would say the same about that one.
One thing we have to remember is that these guys get hired because the owner likes their style of golf course, what they do and what they have built. I think an owner would be upset if they hired C&C and they built something that looked like Nicklaus did it. I think all architects (Doak and others included) have styles and preferences that they gravitate to. Whether they admit it or not, if you see enough of their courses, it is true and maybe in part for the reason specified above.
By the way, for those who might argue that these architects don't worry about a style or preferences and just try to get the most out of a site, I would suggest that they still can do that but they often do it with a certain style, etc.
Just my opinion.
Mark
