As both a golf course superintendent and a connoisseur of classic golf course architecture I can say my affinity for the golden age does not make me a better agronomist. However there is more to being a golf course superintendent than agronomy and Mr. Jeffreys is correct when he simply states "appreciate, respect, and uphold the intent of the architect." I think a superintendent that loves classic architecture is better suited when possible to protect the course from the whims and passing fancies of committees that do not have the best interest of the course/membership at heart. Most superintendents have a connection to the course/property they manage and over time this connection can develop into a deeper love and appreciation for its roots and history, thus one doesn't need to love classic architecture right away in order to eventually come to love and appreciate it if/when managing a classic course.
My two cents,
