Many years ago at an ASGCA meeting, and after reading "ground game this, ground game that" right here on this site, I took the opportunity to ask him what kind of design might make him use the ground game on the approach. He thought a second, then said something to the effect of, on a long, downwind par 4, with a 2 tier green, higher and a bit narrower in the back, that he preferred to aim for the bigger front portion of the green with less slope and "chase it up the hill." I later concluded that making that tier slightly concave would really enhance that play.
So, from that point on, I laid out, or on a reno, found the longest downwind par 4 and designed it that way. I was always surprised at how many people would argue that point. For me, if JN thought that was a good way to introduce variety in shots away from the standard high flight, high spin shot, it was enough for me.
Similarly, I asked him what the smallest target on a green he would aim for was, and his answer was 40 foot diameter, if he had a shorter iron. Again, I designed my minimum green lobes at at least 45-50 feet diam., allowing for collars and some grow in over time. Again, I was always amazed at how many club players would tell me they would aim for smaller targets (obviously, Erik B and several others weren't around to back that up, LOL). I would be there saying, "Well, Jack won't aim for that, so I doubt you should." But, again, many seemed to think their strategic thinking was better. Again, LOL.
