Isn't there a profound implication here for architecture? If JES and I are right, isn't the only way to gear down the equipment to make the courses ask for equipment that SPINS MORE (and flies a shorter distance)? We don't have to legislate this awful equipment out of existence, but just make it sensible for pros to turn the clock back themselves.
So, that means the USGA, via its inaction, has taken away the fun of wide courses for professionals, but c'est la vie.
And, by the way, I just did a quick count. There were 58 rounds in the 60s in the 97 PGA. I was there. It was a very hard set up. Davis shot 3 66s! The greens are the same. The rough wasn't graduated. It was a small amount shorter, but the big difference is they could still turn the golf ball ten years ago.
