I'm certainly no expert, but in my limited experience and off the top of my head I've played both Nicklaus and Dye courses that because of certain design elements suffered from poor maintenance which affected both the playability of the course and the aesthetics.
Off the top of my head Loxahatchee in Florida comes to mind as a course that has had to undergo a lot of changes simply because the original design was too hard to maintain and not well thought out and this was a course rated in the top 100 during it's first few years of existence. Some of their problems relate solely to turf issues, but others relate to the endless mounding used to frame fairways and the bunkering used, #17 coming to mind, those bunkers have been redone at least twice if I remember correctly. I also think that the 10th and 11th holes had issues regarding pine trees near green sites that affect the turf. Both holes look great, but had problems because of routing.
I also think that Pete Dye who has done brilliant work also sometimes doesn't leave behind a course that is easily maintained. To name just two, the course at Amelia Island and at the Marriott at Palm Springs in my experience on at least two different visits were poorly maintained and it seemed like the designs were both forced without any thought as to who was going to have to maintain them.
On one hand I could blame financial problems at Amelia Island possibly affecting maintenance, but in the case of Loxahatchee, Nicklaus called this course his home course for a while and was very involved in day to day operations. I am sure the maximum effort was made, but to this day they still seem to be having trouble getting it right.
I think part of the job of an architect is to think about what happens to his work after he leaves and unless it's a private course whose owner has an inexhaustable supply of $, he should be thinking about whether or not the course can take care of itself to a certain degree.
The move towards naturalism employed by Coore and Crenshaw and Doak may by defnition avoid these types of problems, but in Fazio's case, again in my limited experience, his designs seem to effortlessly avoid the issue altogether without sacrificing offering a test of your game and providing an enjoyable visual experience.
I'm sure we've all played courses that have slopes in certain areas that are so steep that mowing them must be a dreaded experience each day for the crew, and others where the grass simply won't grow because the tree line wasn't properly accounted for. I have yet to come across that on a Fazio course.
