For all the years that I've been hanging out on GCA.COM I've read the many mild knocks on Seth Raynor's work because he "stuck to the same music." The knocks are never too loud, I guess it's hard to argue when his courses are so beloved and he has ten courses in the top 100, including his involvement at Piping Rock and NGLA.
I've always felt these mild slights were unfair. Raynor was hired by guys in New Jersey, Connecticut, Florida, Charleston, Pittsburgh, Cincinnati, etc. etc. to build the holes that Macdonald deemed to be the best in the world. He built courses at a time when there was no commercial air travel and getting from place to place throughout the US was not easy. Few people in Pittsburgh would ever expect to play many of Raynor or Macdonald's courses; building one of their own would make perfect sense at the time to the leaders of these golf clubs.
Raynor was never hired to take a piece of land and "find" the best possible holes; he was hired to build in a template-style. Using his engineering skills, he did so in a masterful fashion. An artistic fashion.
He did not play the same music. He used a lot of the same chords, but arranged them beautifully in hundred of different songs. And guess what? People still love his music; it is timeless. If that bothers Raynor critics or even causes some architects to strike out in their career determined to build holes in a non-template approach, so be it!
