I think the most over rated course attribute on this site is its design. I think that much of what repeated plays at a beloved course reveals to us has less to do with the architect's work than it does with the qualities of the site in its natural state, with changing weather/wind patterns, with the vagaries of shot-making for every individual golfer, shot by shot and round by round, with happenstance and randomness, with good and bad choices regarding maintenance, and with the deeply interested but gentle gaze that love itself produces in us. I think that every architect who has a solid and personal understanding of/insight into the fundamental principles of good giolf course architecture and who is dedicated to making these manifest on the ground should be thanked for the gifts they give us; but I think said architects are responsible for less than half of the design, i.e. less than half of what we experience on their golf courses.

Geeze, Peter. I have been formulating a response to this question for a few days and was just about ready to write my answer... (I was going to say the ground game, because so many locations don't allow for sensible use of a ground game) and you have to blow us away with that inightful observation.
