I like most of Sean's ideas - particularly those in regard to restraint - fewer bunkers, less frilly eye candy, etc - but I think he is misunderstanding the concept of defending par at the greens. What this concept means to me is that the green complex should be designed in a manner to favor thoughtful play - hitting the correct side of the fairway, choosing the correct side of the green to miss, etc.
It does not mean to ignore other elements of the course - fairway bunkering or hazards, routing, etc - but rather to utilize the design in the green complex to bring out the best in these elements.
When I think of someone NOT defending par at the greens, I think of someone who uses hazards to merely penalize wayward shots, or merely offer something that may not be of value to challenge. Ironically enough, I think it means someone who specifically designs for the frilly elements Sean decries!
Love to hear more thoughts, especially Sean's.
