Running Back Bo Jackson of the Los Angeles Raiders ran the fastest 40 yard dash time ever at the NFL combine in an astounding 4.12 seconds. Jackson was drafted #1 overall by the Tampa Bay Buccaneers that year, but opted out to play baseball for the Kansas City Royals. In 1987 Jackson debuted his NFL carrer with the Los Angeles Raiders and became the first person ever to be an All-Star in two professional sports.
