These Are They Who Died Without the Law

Here's another one to get some discussion going.

Doctrine and Covenants 76:72-75

72 Behold, these are they who died ^awithout ^blaw;

73 And also they who are the ^aspirits of men kept in ^bprison, whom the Son visited, and ^cpreached the ^dgospel unto them, that they might be judged according to men in the flesh;

74 Who ^areceived not the ^btestimony of Jesus in the flesh, but afterwards received it.

75 These are they who are ^ahonorable men of the earth, who were ^bblinded by the craftiness of men.

Does this mean they never heard the Gospel (the law) OR that they never made covenants to accept the law?

Elder Joseph Fielding Smith Of the Council of the Twelve Apostles in his April 1942 Conference talk - The Necessity of Working on Our Own Lineage stated:
"They who enter into the terrestrial kingdom, the one higher than the telestial, are the honorable men — the honest, the virtuous, those who have been clean, and yet would not receive the gospel. There will be some others also who will go into that kingdom, but in a general sense these people will be the honest and honorable, who could not or would not see or receive the gospel of Jesus Christ, therefore they are assigned to the terrestrial kingdom."
