Has an Olympic Basketball (Men) game ever ended 98-74?
Exactly once. On January 1, 1956, Australia beat Singapore 98-74, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 98-74 in league history.
That makes 98-74 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 99-74 has happened never and 98-75 has happened 1 times.
