Jackson racked up nearly 2,800 rushing yards and 16 rushing touchdowns in four seasons for the Raiders before a hip injury cut his NFL career short. However, he strung together an eight-year MLB career, primarily with the Kansas City Royals, where he smacked 141 home runs and 415 RBI to go along with one All-Star appearance.
He's the only athlete to be both an NFL Pro Bowler and MLB All-Star as so many have considered Jackson to be one of the greatest athletes of all time
