Even though I strongly believe that an event of the magnitude of the National Open should not abandon the classic and historic old venues, I don't think it is an absolute proposition. In my post above, I may have given the impression that I don't believe that new great golf courses that are in sympathetic design to the features and strategies of the old classics where the open has been held, can't be built anew. When a great one comes along, it should be added to the rota. I just don't think the older classics that can and do still hold the event should be abandoned, as we don't abandon our old touchstones of history.
IN that regard, I do think that the B&I has moved the needle so much that the game is caught between two eras, and the powers that be who set the courses up are nearly stuck in the mind frame of the typical narrowed FW fast but not so undulating greens, etc. They had resisted that model to some extent at Pinehurst #2 and thus were able to bridge the gap between the torture chamber bowling alley rough infested set up, and the more classic course that #2 is. They will have one more opportunity to do an atypical set up with Chambers Bay. In my mind, the advent of CB is a homage to a classic links-like course that gives the USGA a chance to reach back to classic era golf with the presentation on something brand new, and built for the crowds etc. It seems to be a bridge between the TPC model and the older classic seaside venue, even if the features are manufactured, not natural to the site.
There are obviously new courses that we can think of that have classic qualities that we would like to see the National Championship contested upon. You know all the usual suspects. But, they are for the most part built in remote locations, don't have the grounds or infrastructure, etc. They tend to be either wealthy small membership enclaves, or the Bandon Resorts, Sand Hills, Ballyneal remote of the country. So, the respect for the classic design and presentation is there with some archies, but the realistic ability to hold the toon-a-mints are not there.
In my mind the jury is still out on the Erin Hills selection. That is a definite wait and see... It has many facets that I think still need analysing. Is it an homage to classic era golf? aaaah I'd say at this point not so much, more study is necessary for me to make a fair opinion.
