It's been said to be a successful golf course superintendent (greenkeeper) one must play golf in order to see and experience the course and its conditions from the players perspective. I agree playing one's course is critical to understanding the impact golf maintenance practices are having on playing conditions, however that doesn't necessarily mean a superintendent needs a handicap index of 3.1 to be a good superintendent. I know many successful superintendents that enjoy playing the game with a wide range of handicaps, and I think we can draw a similarity to the architecture question.
In other words, golf course superintendents do not necessarily need to know and understand golf course architecture on the same level of the architect to properly care for and provide optimum playing conditions of their course. However those superintendents that embrace the golf course architecture and design of their course will position themselves for success above those superintendents that do not. I have spent the past 11 years caring for Carolina Golf Club and I have made every effort to read as much as I can about Donald Ross, talk to those with experience and knowledge about Mr. Ross, and travel and play as many Ross courses as I can throughout the Southeast in order to have a better understanding and working knowledge of the principles and philosophies of his work.
Some of my most fun and fond memories from the 2008 restoration was spending time with Kris Spence listening to him dictate the thought process and theory behind this feature, bunker, etc. and how the player should approach playing the hole. I'm a golf junkie that happens to be blessed to be a superintendent. I play, watch, read, collect, and etc. all things golf, but I also know many successful superintendents that do not approach the game the same way I do.
Thanks for letting me share!
