Bill,
I think Bill McBride was agreeing with you.
If you meant me - it's only a guess from the photo, never seen the hole in person. I could be wrong, and 'liberal' might be an overstatement, but just how much of the Redan concept is lost if the green is as it appears in the photo - pretty tame with what appears to be a raised rear section?
George, 1999:
What more accurate way to describe a ‘Redan’ than Macdonald’s own words? ‘Take a narrow tableland, tilt it a little from right to left, dig a deep bunker on the front side, approach it diagonally, and you have a Redan.’ Bear in mind when Macdonald says ’tilt,’ he means it. At National, hole #4 falls over five feet from front to rear.
