An honest question: if many interesting hole locations have truly been lost because of modern green speeds, which hole locations were the collegians playing to recently?
In other words: maybe as important as the hole locations that have been 'lost' are the many hole locations that are 'left', ie that are still there and still available despite the modern green speeds -- and there must indeed be many of those left for Pasatiempo to be able to host the Western Collegiate, or to have countless daily fee golfers (including those from this board) playing and praising the course so highly.
All of which is to ask again: if tens of thousands of golfers can still happily play the course each and every year, what's wrong with leaving the greens just as they are, since many hole locations obviously remain? Conversely, if some of those hole locations in common use today are actually dull/unsatisfying or problematic despite still being playable at modern speeds, doesn't the problem lie more with the original design than it does with modern green speeds?
Are we simply assuming that Dr. Mac could never go wrong, and that every green on every set of greens his genius ever designed were perfect, ie with 5, 6 and 7 interesting and challenging and playable hole locations, if only they were maintained at the 'appropriate' speed?
