Does the fact that the USGA decided to leave Pebble Beach #14 alone speak well to the possibilities that they'll leave Merion East #12 alone in 2013?
Mike Davis said, "when you start messing with greens and bunkers... This isn't our golf course, we're only guests for a week".
I'd love to see the US Open play Merion 12 (and 15, for that matter) play as-is. They're fantastic green complexes and I don't think they should be changed.
