I'm thinking of an early C&C, the Crenshaw course at Barton Creek. Offhand, I'd say there are at least seven front to back sloping, fall away greens - 1, 3, 4, 6, 8, 9, 16, mayxbe more.
I've played there a number of times, and never felt that was a problem. The ground there slopes a lot and C&C just made a decision to let the greens lay naturally over the ground, not built up back ends. They really didn't move much dirt there, particularly when contrasted to the two Fazio courses on the property that get all the great press.
