Michael,
14 is probably the best example on the East Course--what a great short par four! It might be my favorite on the East Course.
9 West is a cool green, but it is the only green on the West Course that is not a Ross original. Ross's green was situated at the top of the hill, pretty much where the snack bar is now. 7 is ultimately benched green on the West Course, as is 1, which follows the two-tiered theme, but flipped on its side. 8 is another one. It is three tiers now, but my father remembers playing it as a kid when the green only had two tiers (the back tier wasn't there). That's my theory on why the hole plays the yardage even though it is well downhill--the yardage plate is to the center of the original green configuration.
Imagine the 15th green on the West Course if they shaved down the back banks to fairway height? I love that hole, but it always kills me to play it because I know how good it could be.
In terms of the Fazio changes, he redid four greens. On the East Course, Ross built greens on high points, well back of the lowest points on the hole. This way, golfers could bounce shots in, and the greens would drain well. Fazio took four greens at high points (5, 6, 15, and 18) and moved them to low points, close to water hazards (5, 6 and 15) or a dip (18). Of course, 5, 6, and 15 washed out constantly in the early years, and the 15th green is constantly falling into the pond. None of these greens are playable for anyone except the low-handicapper.
Michael, how long did you work at Oak Hill? I'm guessing you worked for Jeff Corcoran--he's actually my across-the-street neighbor here in Rochester!
