Has a FIBA World Cup game ever ended 105-73?
Exactly once. On August 8, 1994, Croatia beat China 105-73, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 105-73 in league history.
That makes 105-73 the 240th most common final score out of 863 that have ever occurred in FIBA World Cup. One point away, 106-73 has happened never and 105-74 has happened never.
