Kansas City Chiefs

Despite losing to the division rival Oakland Raiders twice in the regular season in 1969, the two teams met for a third time in the AFL Championship Game where Kansas City won 17--7. Backup quarterback Mike Livingston led the team in a six-game winning streak after Len Dawson suffered a leg injury which kept him out of most of the season's games. While getting plenty of help from the club's defense, Dawson returned from the injury and led the Chiefs to Super Bowl IV. Against the NFL champion Minnesota Vikings, who were favored by 121⁄2, the Chiefs dominated the game 23--7 to claim the team's first Super Bowl championship. Dawson was named the game's Most Valuable Player after completing 12-of-17 passes for 142 yards and one touchdown, with 1 interception. The following season, the Chiefs and the rest of the American Football League merged with the National Football League after the AFL--NFL merger became official. The Chiefs were placed in the American Football Conference's West Division.
