First, I don't agree with Joe's quote in the first place. I think the golf course itself comprises one of the most special things in golf, maybe the most special to me. The combination between sport and nature is truly awesome. Putting on #2 green at Sand Hills and looking for miles in every direction without any civilization in site .... hitting your approach on #7 at Old Macdonald and then walking up to see not only your shot but the wonderful Oregon coastline ..... These are not things that involve sportsmanship, honesty or history. That connection with your surroundings make golf great much more than those things listed by Joe. For the golf professional, I understand those things being important, but they are not the reason that I play golf.
That being said, I don't think honesty or sportsmanship are dead. At the 5th Major, I was perfectly happy having John K and his partner beat my team soundly. I cared much more about having fun with them and experiencing a wonderful golf course than the status of our match. As a result, we had a nice match and I enjoyed John's company quite a bit. He really is a wonderful guy.
Do less people exhibit sportsmanship today than in the past, yes. I think this is largely due to people gambling more money than they should be and the stupid obsession in the US about winning in sports, versus enjoying the competition. It causes the cheating on the course as well as the manipulation of the handicaps. However, I don't think sportsmanship and honesty are dead. While I hate using tournament golf as an example, just look at how Mickelson acted toward Justin Rose at the Ryder Cup. He applauded good play and enjoyed the competition.
I never cared much for the history of golf so John, it may be dead. If so, I am fine with it. I don't care who wins the most majors or where major tournaments have been played. For instance, when I consider my likes and dislikes of a golf course, I don't give much consideration to the course's history. For example, I loved Oakland Hills greens, but I venture that they ruined many of the great parts of the course in making it tournament ready, as it is extremly boring, penal golf from tee to green. I love a lot of things about Oakmont. However, I think many people on this site and other magazine panelists give its penal architecture a pass due to that history. Honestly, without that history, would people really love its 20 yard wide fairways with bunkers of doom/disaster on both sides? Given my choice of places to play next, I would take a trip to Dismal River and Ballyneal before either of these historic venues.
Just my thoughts. Interesting discussion John.
