Jeff - well, few here have ever had any reservations about making suggestions to a masterpiece, obviously. Hell Rich Goodale steadfastly maintains the course would be better with the routing completely reversed, a suggestion made by our own Tom Paul initially. So no, screwing with masterpieces is absolutely accepted here.
My point to my friend Mike was more about the 18th... and that is, if a green would have been better farther to the left, by the bay, don't you think MacKenzie would have put it there?
And the same thing goes for these other, wilder suggestions. I trust MacKenzie got it right.
But it is fun to speculate.
So to that end... your suggestions are interesting... but I can't see them as an overall net gain. 16 tee to 17green/18tee covers some broken ground... hard to imagine a fairway going through that area .. then 17 as a par 3 going in the reverse of the current 17 fairway, well... that's a definite decrease in quality from the current 16 - you wouldn't go over the ocean, just alongside it. The 18th going in reverse of current 16 is interesting, but to make it a driveable par 4 you'd have to move the green away from the water, and that rather takes away a lot of that thrill.
So, let's just say I like what MacKenzie did better. But that is an interesting thought... and it pretty much describes the first three or so holes on the Paul/Goodale Cypress.
