You know, the funny thing is that when almost any architect tells us why he didn't propose (or in some cases, wasn't selected) I take it with a grain of salt. In CC's case, I believe that what they told Whitten was exactly the reason why they didn't do it.
How many times have we heard "only want to focus on one project at a time (I believe CC in this regard, too, whereas most of us are FORCED to work on one project (or less!) at a time......Bill and Ben are not pretentious and always have been totally honest with others and the press. Of course, with their slow southern drawls, I suspect they wouldn't have gotten selected (at least not by Forrest!) because their interviews and sound bites would be too drawn out and long for good TV.......
That said, I would think most tour pros, including Ben, would understand the need for some separation of greens and tees to allow for circulation, and figure they could do it better than anyone based on their experience. It is quite possible from what I have seen of that site, that there might not be any real compromises at all, unless having the next tee 150 feet away rather than 50 feet away is considered a big compromise by them.
