TD,
As any media savvy person knows, its not always the exact words that stick with folks, but I agree it is hard to get that big a group to agree on much. And on some issues, that is on purpose. We are only a society to join together on issues of common good, but design standardization isn't seen as on of those kind of issues. From time to time, we have promoted generally agreed upon things in architecture, like affordable golf, water conservation, etc. We have even promoted the benefit of shorter courses (Bill Amick's Caymen push, Alice Dye and forward tes (now morphed into my push for forward tees at 4000 yards, etc.) Hard to measure if the group message has a huge impact, but obviously, the general direction of golf hasn't changed a whole lot.
And, for that matter, it is fairly obvious that the increased length of golf courses trend will only change course at the rate of the turn of the Titanic. Again, even had we put out a position that not every golf course needs tournament length, I wonder how much impact it would have had? Everyone seems to want a tournament course, for reasons discussed in this thread.
But, as noted, not all architects insist on it. However, I did stand up at ASGCA one year and ask how many guys had actually been asked to design an 8,000 yard course, and was surprised at how many had been. (and how many had complied, which I assumed would be the case) The only guy I recall publicly promoting that was Roger Rulewhich, which seemed to be part of his ongoing RTJ legacy, a la the Alabama trail (although I don't recall what those courses top out at...I know they are long)
I have a design underway here that is going to be 6600-6800 yards tops (if it actually gets built). My China stuff is "required" to be over 7000.
My real issue these days about 7K is that it seems to be a 'tweener distance between the best players and the next class. Most club players I talk to find 7200 to be just fine, so after a period of longer back tees, I would suggest that as plenty long for most courses. Even NCAA courses don't set up longer than that to protect the field, and they are supposed to be the longest hitting group around. Any pro tour course at 7500+ yards is said to shut out most of the field.
So I hate it when a consultant recommends a 7000 yard course. Just seems out of date. But, in general, I don't have an issue with building a 400 sf back tee for the few who play there, as long as it doesn't increase turf acres a lot, or increase costs too dramatically (which no doubt, a 7600 yard course would)
I don't really see how the majority of it is the architects fault. I do think the industry should be promoting another class of golf course that doesn't need tournament tees for that 1%, using the analogy that in the restaurant biz, general menu restaurants seem to lose out to specialty places, like Mexican, etc. Maybe the golf course market needs to mature into something other than the one size fits all mentality. Tee it Forward is sort of that kind of initiative, but we will see if that kind of thinking sticks, or fades away (getting ASGCA to agree is one thing, getting all the associations to agree is 10X tougher)
