BTW, you're right in that the terrain around the original Dell green is far more severe than at Erin Hills, but I think it may be more likely to have an awkward chip at the Erin Hills hole, because the ball is more likely to stay on the side of the bank than at the original where the hillsides are so steep and the ball usually bounces down onto the flatter area on/around the green.
While this might well be true...this photo of my 8 year old son will show you that the ball doesn't always bounce down the hill at the original Dell... he did get up and down...
