Agree it took a few people to go out and do it.
Also understand the nay saying. For every great idea that catches on, there are probably 99 that are pure rubbish that have forgotten the lessons of the past, or are different just to be different. I have seen landscape architects propose Elm trees, seemingly completely forgetting what happened decades ago.
One I was thinking about the other day was design inspirations other than form follows function, i.e., designing greens in the shape of a state, country, or continent just to be different. That has been done a surprising number of times. Glad it hasn't caught on big time.
On the other hand, Mike Keiser willing to go cartless is not widely adopted, but a great idea nevertheless, as is his resort concept. A lot of destination resorts have failed, but success seems to be a visionary idea AND getting the details wrong. Or, no one was going to fly across country to play a course similar to what they could play at home, so it had to be different, just to be different.
And the bunker washouts are a good example of my big world idea. Architects did them, golfers liked them, but they presented a maintenance issue. Someone also went out on a limb to start producing bunker liners in response, then, someone else produced them to be better (they thought anyway). Now, bunker liners are more or less standard and architects can design nearly any slope and depth they want. Whether its a good idea on your local muni remains up for debate.
And there you go, I can't stop naming examples of great new ideas, bad new ideas, good ideas poorly executed, good ideas that lead to other good ideas, etc. Yes, it took someone to go out on those limbs, but the entire process seems sort of random most of the time.
