FILE–Franco Harris (32) of the Pittsburgh Steelers eludes tackle by Jimmy Ware of the Oakland Raiders on a 42-yard run to score the winning touchdown in the American Conference playoff game in Pittsburgh in this Dec. 23, 1972 photo. Harris’ “Immaculate Reception” came when a desperation pass to a teammate bounced off a Raiders defender. Harris caught a miracle out of thin air to start it. The 1980s ended it. For more than half a decade, it was a rivalry that thrived like no other in the NFL, one thata mere playing field couldn’t contain. (AP Photo/Harry Cabluck)
