“Jack played it more as a cookie-cutter setup,” Davis said. “What we’ve tried to do is more respectful to architecture, so we’ve done that here. In ’04, some of these fairways were so narrow that you had fairway bunkers 10 yards out in the rough. That doesn’t make sense.”

He referenced the 1950s, when Joe Dey was running the USGA and Richard Tufts was the president, and there was a blueprint for the U.S. Open.

“It didn’t matter if it was Oakland Hills or Winged Foot,” Davis said. “There would be fairways a certain width, thick rough, fast greens.”

But it was the toughest test in golf. More times than not, it was about survival.

The U.S. Open is not big on slogans — there is no name attached to the silver trophy. Davis says the “toughest test in golf” was a label from years back, although the USGA certainly didn’t frown on it. He has never heard anyone at the USGA talk about protecting par, but a winning score at or above par seems to bring smiles.

The ultimate test?

Davis once denounced such an idea at Congressional on the eve of the 2011 U.S. Open.

“I think what we’ve stated over the years is that we want it to be a very difficult challenge,” he said that day. “But I’m not sure we’ve ever used the ultimate challenge. Maybe somebody else has, but I don’t believe the USGA has.”

And then it did.

Diana Murphy first publicly mentioned it at Oakmont two years ago, and it has become a popular phrase among the blue blazers since then. Jeff Hall, the USGA’s managing director of rules and competition, explained the notion of “ultimate test” as shot-making, course management and resolve both physically and mentally.

“Make no mistake about it,” Hall said. “The U.S. Open is a grind.”

That’s an identity that should never change.
