The 13th hole at my club has its green benched into the hillside. It slopes from back left down to right front. The left side is always higher than the right side, so it is an advantage to come into it from the right, which of course is from the rough.
Macan preferred greens that sloped every way but back down to front. This meant that often you were at a distinct advantage to being on one side of the fairway vs. the other side. You also were at an advantage if you could turn the ball both directions. I documented Salem Golf Club having such greens. Since courses often let trees take over off fairway areas, much of his design is not realized, because you can't turn the ball in from the left or right if there are heavy stands of trees on the side you want to bring the ball in from.
