Jeff,
At the risk of digging myself into a deeper hole I offer these quotes.
"The principal of the hole is to give the player on the tee a number of alternatives according to his strength and courage. If he plays for the green and succeeds he has an advantage of at least one stroke over the opponent who takes the shorter carry (...) and probably more than one stroke over the player who avoids the carry altogether. But if he fails he is bunkered and may take five or six and lose to the short player who goes around."
"The (...th) is not complicated: Lay up down the (...) side and leave a short pitch to (the) green. Knowing this, players still cave to temptation and play straight at the green either intentionally or via some subconscious refusal to lay up (...). The aggressive route to the hole rarely leads to eagles, or even birdies, and almost always causes round-deflating pars and bogeys."
The terrain, style and nature of the hazards, and size and shape of greens may be different, but I still see the fundamental strategic concept of these holes as essentially the same. Take the risky route over a cross bunker which must be carried in order to attack the green from the tee or lay up off to the side of the primary hazard to set up a short safe second.
Rivieria is 315 yds today, Acacia was 280 yds in 1924 and NGLA was an uphill 262 yds in 1920.
Doubtful that Thomas invented the driveable, highly strategic, short par 4, but he did perfect one version of it. As Macdonald wrote of his Sahara at NGLA, it was based on "the basic principle of all the best full drive holes."
I am pretty sure Langford was familiar with the work of his fellow former Chicagoan Macdonald. And he was after all in graduate school at Columbia Univ. in NY during the genesis of NGLA.
