Random thought popped into my head, and its not that I am suggesting that tough courses equals good architecture. That said, most architects got famous for their tough courses.
Thinking we could divide it up into post 2000, 1975-2000, 1950-1975, and the Golden Age, since its hard to compare between different eras. Yes, there are overlaps in any demarcation like 25 years. And, any true historians might go further back.
Not even sure who to put in the Post 2000 era.
1975-2000 would have to guess JN, Dye, and maybe Von Hagge, since he designed for shadows, etc., and not really golf. Some of those steep banked bunkers got really tough.
The obvious 1950-1975 would be RTJ and maybe Dick Wilson.
I am a bit fuzzy on the Golden Age.....yes, Tillie had his man size designs, but was that a constant? Anyone else out there, like Maxwell who might get consideration?
Would be interested in any guesses as to the primitive age, and of course, any different opinions on any era. The point is discussion, as always.
I would also guess there may have been some lesser heralded archies in each era who unknowingly built hard courses because they aren't golfers.......
