Chip,
In order for Dornoch to be outside of the world top 10, one has to have 10 courses ahead of it. Hey, call me smart
These eleven courses - NGLA, CPC, The Old Course, Royal Melbourne West, Pine Valley, Sand Hills, Royal County Down, Merion, Pebble Beach, Oakmont, and Shinnecock Hills - all seem in a clear class above, so Dornoch is on the outside looking in in my book.
Is it because it is 'too easy'? I'm not sure but coincidentally or not, I would say it is the easiest of the twelve courses mentioned in this post. Of course, a big part of the reason is that (like many UK courses) visitors have no option but to play a relatively short course. Is there a par five from the visitor's tee at Dornoch? Maybe not and if not, then 9 and 12 as two shotters give the course teeth relative to par.
Playing Dornoch 600-700 yards longer would probably make the topic thread a non-starter so what course are we talking about? The one we can play or the one we can only imagine? Don't we have to stick with the one that we can actually play?
Chip, anecdotically, I would have to agree with your premise. The Morrissetts first went to Dornoch in 1983 and all four of us broke 80, which has never happened before or since on a world class course (John was even 13 years old at the time). Dad had a career round in the low 70s and joined the club within two hours of walking off the course
I remember having a lacklustre 75 in still conditions in another round and being disgusted with my poor play as an 8 handicap. That feeling most assuredly wouldn't exist at any of the other eleven courses listed above.
However, in an effort to look at it beyond a handful of personal experiences, I personally think the back nine lacks another world class hole (or two) and thus, I simply don't have the same super high opinion of it as 90% plus of the posts ahead of mine.
Dornoch is very solid with no weaknesses and I think it may even be considered straightforward (which may explain in part why so many Americans love it). It doesn't have the quirk of Royal St. George's or The Old Course or Royal County Down. While everyone talks about the green complexes, I don't as I don't think the interior green contours are but so special. However, what is very special are the fairway contours and the fairway contours on a hole like 12 would be a major focus of any course profile that this site ever did on the course.
Cheers,
