The "problem" is that golf courses are different from one and other. Of course, that's not really a problem, but rather one of the great virtues of golf. Conditions – rain, wind, and so on – vary. That cannot be controlled – a good thing.
I like the idea of a somewhat more-difficult-than-usual course for the US Open. I'd also like to see it conducted on great courses. However, I'd like any beefed-up difficulty of a course used for the US Open to simply add to what's already there, rather than change its character. In other words, I don't like the idea of taking a great course that has a normal strength of defense A, and then adding deep rough as defense B.
Unlike most of you, I'm not personally familiar with Marion (although I suppose I might be able to search this site and learn something about it
), so I don't really have an opinion on how Marion should be set up for the Open.
Skipping ahead to next year, I like the idea of going back in time at Pinehurst. My vague recollection is that for the 1999 Open at Pinehurst the USGA lengthened the Bermuda rough, but that in 2005 they cut it much shorter. My understanding is that there will be no Bermuda rough in 2014 – but rough of a different sort. So, if Pinehurst #2 as originally designed was a great course, then going back to the original defenses ought to be a good thing. We'll see.
