Pat,
I am not going to state numbers, but Pete Dye did a study about green speeds which I am sure you are familiar with. A good deal of his study was based on video which I question as a reliable method of determining green speeds, but he thought 7 or 8 was fast 40 years ago.
Regardless, the argument is baseless considering the other advancements in technology that should help to take those bunkers out of play.
Jim Kennedy,
I wrote a real nice response describing my understanding of your position and it vanished.
Summary: I now understand your position that this effort by the PGA Tour and Muirfield Village may help increase the randomness which hazards should characterize, but it actually moves away from the proper treatment of hazards. That is, they are hazards, and hazards are not to be manicured.
If I summarized it OK, I agree with you 100%. I only had my eye on the randomness issue, thus the difference.
