Led by quarterback Len Dawson and a staunch defense, the AFL champion Kansas City Chiefs defeat the NFL champion Minnesota Vikings, 23 - 7, in Super Bowl IV in New Orleans. In the first two Super Bowls, the NFL's Green Bay Packers easily beat the Chiefs 35 - 10 and the Oakland Raiders 33 - 14. Super Bowl III on January 12, 1969, featured one of the greatest upsets in sports history when the AFL's New York Jets downed the Baltimore Colts, 16 - 7. The two leagues are set to merge later this year, so today's Super Bowl is the last NFL-AFL matchup. The Chiefs' one-sided victory over the Vikings puts to rest any claims of NFL superiority.
