And why is a ball that hits the foul line or foul pole a fair ball? (needs to be renamed to the fair line or fair pole)
That’s racist!
Are there any sports other than football and basketball where the line is "out"? Every other sport I can think of requires the whole ball (puck, whatever) to cross the entire line before the line is considered passed.
E.g., soccer: the touchlines are "in" and the entire ball has to cross the entire line to be a goal; tennis: the lines are "in"; baseball: foul lines/poles are "in"; hockey: entire puck has to cross entire line to be onside (or clear the offensive zone), be icing, or be a goal; etc.
