I hate the idea of every group having their very own personal ruling official. I doubt that it will be a blind draw and some officials will get the celebrity groups with massive TV coverage while others get the non-contenders. Every official will have a different opinion and be subject to the natural influences of human nature. A much better solution would be one official per hole so at least some consistency could be established.
I do hope that players are allowed to question a ruling of their personal official and bring in a second opinion.
This is the US Open and much like the World Series, Super Bowl or NBA Finals there is a very limited number of people qualified to make calls on a world stage. I am positive there are less than a dozen golf officials in the world ready to make the big call. There are going to be some good people making bad calls. But then again, this is a dream scenario for the USGA because they will be the story.
