Has an Olympic Basketball (Men) game ever ended 98-52?
Exactly once. On January 1, 1968, Brazil beat Morocco 98-52, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 98-52 in league history.
That makes 98-52 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 99-52 has happened never and 98-53 has happened never.
