the timing of President Kimball's admonition, starting in 1974, that every young man should serve:
The question has been often asked, Is the mission program one of compulsion? And the answer, of course, is no. Everyone is given his free agency. The question is asked: Should every young man fill a mission? And the answer of the Church is yes, and the answer of the Lord is yes. Enlarging this answer we say: Certainly every male member of the Church should fill a mission, like he should pay his tithing, like he should attend his meetings, like he should keep his life clean and free from the ugliness of the world and plan a celestial marriage in the temple of the Lord (Spencer W. Kimball, Planning for a Full and Abundant Life, Ensign, May 1974, 86).
Since then, you had highly recruited guys like Glen Titensor, Lance Reynolds, etc in football, and Steve Craig, Craig Christensen, and Devin Durrant in basketball who were stars but still served. I don't recall anyone since 1980 using the Osmond rationale for not serving (GAs giving them a pass due to visibility).
k2coug was indeed making stuff up.
