I haven't read the whole thread so please excuse any repetitive opinions.
First, NGLA, and most of TOC, are the epitome of wide fairways that, if you miss off the tee, "it follows you all the way to the hole". This, IMO is due to the angles and other excellent architecture that is ON THE GROUND - including the green complexes.
Augusta National was like that until equipment and player ability forced them to add the "second cut" although that is really less penal - more just to make it harder to spin the ball to those great greens.
As for the great parkland courses such as Merion, Oakmont, Baltusrol, TCC and Winged Foot, I'm afraid the real deep stuff has become necessary for championship play.
Personally, I think it is awful for regular member and guest play. It adds up to 30 minutes/round and takes much of the fun out of the experience IMO. Under even semi-championship conditions, a four hour round without picking up when appropriate and only minimal reading of longer putts is impossible unless the group is all members.
For the last two weeks, Merion has been, basically, unplayable for the members from anywhere other than the short grass - of which there is much less, anyway. I sense that the analogy will be made with Winged Foot in 1974. "Drive for show" may need to be amended to "drive for dough so you have the chance to putt for dough".
To paraphrase Lee Trevino, contestants that are chipping and pitching for birdies won't be in the hunt for very long.
