We've been answering two questions here, one of which Bill didn't ask.
There is no doubt that, in the real world, the environment surrounding a golf course -- quality of competition, level of junior support, access for young players, teaching staff, etc. -- has more impact on producing successful players than architecture does. But as I read Bill's question, he wanted our opinion on which course would produce the best player if all those other factors were equal.
In that regard, I think it's more important to look at who has won on a given course than it is to look at which players grew up there.
