Ted:
I've not seen the course at French Lick, so if that is the entire basis for your question, then I shouldn't respond. However, I know enough about Pete to have an opinion on the title to the thread.
Honestly, I don't think Mr. Dye has changed his thinking much in 60 years. And that's not meant to be derogatory, in any way. I don't think I have changed my thinking too much in 30 years, and don't expect to change it much in the next 30, as far as what I'm trying to do in golf course architecture.
Mr. Dye has always believed in challenging the best players, but has always tailored that to whether he is trying to challenge the best amateurs, or the Tour professionals. Crooked Stick was more of a club for Pete's peers [scratch-level amateurs], but at The Golf Club, he had Jack Nicklaus and Tom Weiskopf out there in their 20's, telling him how long it needed to be. I believe the course was built at 7300 yards back in 1967!
From all that I've heard, French Lick is just an extension of that. Why that client would want a course fit for Tour pros, I don't know, but Pete is completely right to think that it would have to be as long as it is, to challenge the pros the same way that The Golf Club challenged them 50 years ago.
By the same token, while many of Mr. Dye's clients ask him for a tournament-tough course, he doesn't always operate that way. Long Cove is a great example of a course for a housing community, tailored to the people that are going to play it. That new course you described recently, outside of Indianapolis, is perhaps another. Pete is not at all incapable of building courses at the scale of mortals -- as some of our immortal players - turned - designers are. But if that's what you want from him, you have to ask clearly. If you say anything about testing good players, then it's going to be tough as nails, because Pete knows how to test good players.
