Patrick:
No doubt, Mr. Dye fell back on a few favorite ideas later in his career, like the short par-4 with the blind green at Old Marsh. [I believe it's the 5th hole, not the 6th.] That hole was a copy of the 5th at Long Cove, where I happened to work, which was the first time he'd built such a hole. I believe it was inspired by the 14th at North Berwick.
He also built several Redan holes, and of course the many par-4 finishing holes gently curving along a lake.
Pete had a lot of very flat sites where he had to create holes from scratch, and he needed ideas to start with. It's much harder to keep doing that over and over again without repeating yourself. Personally, though, I was sad to see it. To me, what made Pete a great architect was having the guts to build that hole in the first place ... not repeating it on ten other sites.
