It's sort of like the "nothing good happens after midnight" lesson that mom tried to impart (unsuccessfully, in the main) to me. The closer you live to the edge, the more likely it is that you'll go too far. I don't think this issue is controlled by Shinnecock (or any other host course), nor do I think it is limited to Mike Davis. They've had setup issues before in the Tom Meeks era and I simply attribute it to the institutional affection for the severe setup. One cannot control the weather and if you are torturing the turf to get maximum speed and trampoline effect, bad things can pop up rather quickly. I should mention that I've worked with both of these men and that I've always had a great deal of respect for Meeks, because he would "wear the jacket" if there was a problem with a punitive setup. He also "owned" the softer setup at Olympia, but the golf course took a pounding in the media anyway. The same is true of Davis and Erin Hills, it seems to me.
I think they got lucky with Koepka as a winner, because he had the right mettle during the Saturday Slaughter and managed the golf course quite well on Sunday, so the spotlight could drift away from the near debacle with the setup decisions. They managed to identify the best player in the field and didn't wind up with a random lucky winner, which has happened in the past.
