Like about every other aspect of life, technological advances have not been able to be stopped, and the game of golf, especially for the pros, has been changed. The pro game is simply different now than it was back in 1974 when Irwin won at WFW. Yesterday's most challenging and best courses need to adapt if they are to continue to challenge the professionals.
I remember watching Angel Cabrera, at Oakmont two years ago, hit like a 390-yard drive on #12. Clearly, that would have never happened back in the day. Yet, his winning score was +5. I'm guessing the course's defense now compared to earlier times is incredibly high rough, narrow fairways, and fast and undulating greens. It seems to me those traits are now needed to test the professionals, because obviously length no longer does.
I sincerely wish the ball wasn't going as far as it is, but sadly it's a reality that will not change. I think, if an architect has marching orders to create a stern test for the world's best players, he needs to beef the course up in areas other than yardage. Of course, once the golf course is built, the super needs to do his part to get the rough up and the greens firm.
