For a brief period between 1987 and 1990, Bo Jackson was as larger-than-life and exciting a player as the NFL had ever seen. Among the best athletes ever to play in the NFL, Jackson was big, strong, and blazing fast – and he also was a Major League Baseball All-Star. An Alabama native who won a Heisman Trophy at Auburn, Jackson had decided to play baseball despite being picked first overall by Tampa Bay in the 1986 NFL Draft. But he joined the Raiders the following season, and was an instant phenomenon, averaging 6.8 yards per carry and running for a memorable 91-yard TD on Monday Night Football. On and off the field, Jackson seemed destined for greatness. In Nintendo's Tecmo Bowl, his likeness became legendary, while images of him as a two-sport-star – as part of his “Bo Knows” Nike advertising campaign – seemed to be everywhere. But Jackson, who made a Pro Bowl in 1990, suffered a hip injury that abruptly ended his NFL career – and he’d go down in sports history as one of the greatest players whose potential was never realized.
