I'm not so sure the course should be called Old Macdonald. It's catchy, but it implies that the course will be rebuilding templates from what another borrower took from original concepts. If credit should be given to anybody, methinks it should go to the original designers/discoverers.
I have a strong belief that this new course will look much different than the engineered look of National. If I may paraphrase Tom Doak " There will be nothing that resembles Raynor's style." and, "First we found holes that were already there in the land." Besides, the land in Bandon is pretty darn special, why Copy and Paste imagery when a designer can retell a story in his own words?
So, to answer the question, the concepts that are being chosen are proven concepts so I think we'll have another winner in Bandon. (IMHO)
