TEPaul,
Like trees growing, greens shrinking is an almost imperceptable process and problem, that in the course of just a few years can alter the configuration of the green and the play of the hole.
What surprises me is not the 6 inch incursion of the rough or fringe, but several feet of lost footpads in a given area.
Perhaps that area requires special attention while mowing, or doesn't fit well in a cycled mowing approach, but, at some point in time, when it's obvious to all but the blind, that condition must be recognized and remediated.
That single revelation should also send the signal that perhaps other greens have suffered the same fate, and a global program should be undertaken to restore the intended lines.
I tend to agree with rkeller, the Superintendent is the keeper of the castle, and as such, is charged with the responsibility of "properly" maintaining the golf course, and this includes preserving the design integrity of the tees, greens and fairways.
I don't think green shrinkage is a budget factor, rather a habit that maintainance staff inadvertantly fall in to in their daily functions.
All too often, the easy way, rather then the proper way, is the path chosen.
But, the ultimate responsibility lies with the "keeper of the castle".
