Adam,
Although I don't necessarily agree, you do bring up an interesting point about Merion.
In essence, there are only a handful of holes where one could logically putt or bump-and run from an appreciable distance onto a green, and then, almost always (except for left of 14) from the very front angle.
Those include 1, 2, 5, 6, 10 (from the preferred right-hand angle), 12 (if you are deranged and troubled), 14, and 18.
