Gale Sayers, a four-time NFL Pro Bowl running back, was born on May 30, 1943.
Sayers was a standout athlete his entire life. In high school, he set Nebraska's state record for the long jump -- a mark that wouldn't be broken for decades.
He went on to star at Kansas as both a football player and track athlete, earning the nickname "The Kansas Comet."
Sayers went on to play seven seasons with the Chicago Bears, earning Pro Bowl bids four times. He retired from professional football before he turned 30, surprising fans and his teammates.
He finished his career with 4,956 rushing yards and 56 touchdowns, and his body of work was strong enough that he was voted into both the College and Pro Football Halls of Fame in 1977.
Sayers is often referred to as one of the great NFL stars who retired in his prime.
