Going back and looking at the photos, it appears the spun rod bearing failure started with the main bearing failing first. Oil starved or clogged oil passage or some unknown reason stopped adequate flow of oil to the main bearing which supplies oil to the rod bearing. The main bearing starving the rod bearing of oil, caused the rod bearing to overheat, excess wear and then to spin within the rod. Tangs, as you seem to think would prevent bearings from spinning, would not have prevented the bearing in the rod from spinning if this case.
