Has an Olympic Basketball (Men) game ever ended 85-49?
Exactly once. On July 26, 1996, Lithuania beat Angola 85-49, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 85-49 in league history.
That makes 85-49 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 86-49 has happened never and 85-50 has happened never.
