"As legend has it, Jimmy Johnson conceived the idea of trading Herschel Walker during a morning jog. In a deal involving 18 players and draft picks, the Cowboys sent their star running back to the Vikings, who viewed him as the missing piece in their Super Bowl puzzle. While the picks Dallas received turned into Emmitt Smith, Darren Woodson and the cornerstone of their own three Super Bowl wins, Walker never had a 1,000-yard season for the Vikings and never won a playoff game in Minnesota."
