Off we go to a trying time in Pittsburgh Steelers history. On this very day... Stevie Wonder was tops on the radio with “I Just Called To Say I Love You”, Teachers was No. 1 with movie goers and born that day was Baby Fae, the first infant subject of a xenotransplant procedure and first successful infant heart transplant, received the heart of a baboon. Meanwhile, the 3-3 Steelers were coming off of an embarrassing loss to Dan Marino and the undefeated Dolphins and traveling to San Francisco to take on the undefeated 49ers.
