Some post on here got me to thinking about second courses built next to existing, great courses, and how I had seen few that begin to match the original. I'm talking about courses built on nearly the same land as the first, often by the same architect, with nearly the same chance of success. But I believe few succeed. In fact most are total failures.
Some examples--The second course at Ballibunion fails totally, in my opinion, to come even close to the original. In the US, the Irish Course, built next to Whistling Straits, on the same basic land both by Pete Dye, doesn't make it.
In my opinion, the best success is probably Sunningdale, where the Old and New are both tremendous. Maybe this is the exception that proves the rule. (I think that multiple courses built in a complex like Pebble or Bandon are different than the right-next-door examples I am thinking of.)
If my premise of failure is generally true, why is this? What other examples can you think of?
