Mike,
ANGC was always intended to be a championship venue, hence, fine tuning after opening day would seem to be natural progression.
What was the amount of time AM spent designing and building ANGC ?
Could it be that the changes that followed opening day were a result of, initially, not fully taking advantage of the terrain at ANGC due to the limited amount of time spent in the design and development of the golf course ?
Could it be that AM's design theories were brilliant in the context of the club golfer, but inadequate in terms of professional golf at the highest level ?
When you view some of the changes, you can't help but think that they improved the golf course, for the members and the Pros.
Moving # 10 green to the knoll was brilliant, and, one has to ask, why wasn't it part of the original design ?
Changing the configuration of # 16 appears to have enhanced the hole, especially in the context of presenting a challenge to the best golfers of the day.
When you examine ANGC and the changes to the course, in a global sense, very few have been made that change the fabric of the course.
Moving # 10 and # 16 green, redesigning # 7 green, # 9 green and expanding some creeks.
But, essentially, the routing and general individual hole designs remain as they were in 1934.
Not long ago I was speaking with a fellow who's played ANGC for 40 years.
The one thing we both agree upon was that 6-9 short years ago we could both play the course from the Masters Tees without much difficulty, but, today, that challenge is overwhelming.
However, from the Members tees, the course remains a delightful challenge.
