The goal of the USGA should be to identify the best golfer. In my eyes that is not their focus. They appear to identify just the straightest hitters.
Like Tiger at Torrey?
I don't think there's a golf tournament on earth that can positively identify "the best golfer". The best they can do is identify the best golfer in a given four (or sometimes five) days, and even then, that guy probably needs a bit of luck to win. An exception, of course, would be Tiger at Pebble in 2000.
Here's my take on what Richard has said (with the caveat that I've played EH, but not Medinah): Given that he hasn't played either course, and assuming that both Medinah and Erin Hills are both excellent tests of golfing ability for the touring professionals, he would prefer to watch an event at Erin Hills, presumably since every hole doesn't look the same.
For my own take, I sort of agree with him, and I'll take it a step further and say that the issue with Medinah isn't necessarily that all the holes look the same, but it's sort of a cookie-cutter-looking course, with big trees lining lush fairways, which we see on television quite often. That has nothing to do with its ability to test the best golfers, which is proven.
I don't think it needs to be said that when it comes to tournament golf, most of us want to see an event that provides some drama and involves the world's best players, regardless of venue. I certainly would rather watch Tiger, Phil, Lee, and Rory battle it out over the final holes over a blowout no matter where the tournament is held. But again,
all other things being equal, Richard would prefer to see the Open played over an interesting piece of property, the likes of which we don't see on TV all that much. At least, that's what I took away from his initial comments. If that's not accurate, I apologize.
