Niall,
Didn't see that, but do agree most players are looking at the contours inside the greens in crafting their shot. Always amazed when I have played with guys like Nelson, Wadkins, Elkington, Colbert, Begay, etc. how they plan on using the contours on the green to get close.
And, in the few Doak courses I have played, he seems to create more of those options than most within the green contours and you really do have to know them to score well. (Have told the story before, but couldn't get my son out to Rawls course for practice....he had a girlfriend (long gone, of course). He was a 3 time district champ, but never got past the Rawls course to State because of that, and in following him, I could tell he was just playing the standard shots when a different approach shot (or chip) was needed.
What kills me, for all the mystical talk of green contours here and among golf architecture geeks is how simply the pros explain their strategy. I asked Lanny about the green front opening. Yeah, it allows him to hit the lower of two clubs if between. If he had to come over a bunker, he looked for the long club and hit it with more spin. If there was a contour he could take advantage of at the top of the green, he aimed for it.
Elkington, when asked about judging or using green contours simply said, "balls roll downhill!"
Colbert almost preferred to come in over a bunker, aiming at the far side of the green and curving it back to the middle (with either fade or draw, one of few who would mix shot types)
Larry Nelson advocated many "spikes" (rolling edges) where hitting the middle of the green was easy, going for a pin was well protected by a ridge that could help you, but possibly kick the ball very much further away, i.e, easy par with conservative play but hard birdie. He never looked outside the green at hazards, etc. figuring he wasn't going to hit them anyway. They all just look at the green contours and that, to me, is as much strategy as planning some kind of bouncing run up shot.
