Rich,
You're brain is "in a box" on this one. 100? Really? I'm not saying I'm a baller, but I shot 95 on my first time around Oakmont from 6900 yards or so. The rough was graduated, at a solid 3.5 inches much of the time. We played 4, 7, 8, 10 and 12 from the tippy tips--way past my pay grade--which added a substantial distance to the blue tees that day. The greens were at what the members were calling, "Open speed", which is to say, slower than normal. The course was also soft, increasing the length in many places.
Michelle Wie shot a 76 that same day from the Blue tees. You can't tell me that another 500 yards and switching the venue to Pebble would equal 24 more strokes for her. The ladies hit the ball straighter than any of those yahoos that played in the challenge. And they can putt better too. 100+ is just out of the question for players of that quality.
