The season ended when the Baltimore Colts defeated the Cleveland Browns in the NFL Championship Game, only to be upset by the American Football League's New York Jets in Super Bowl III. Subsequently, it was the first time in the history of professional football in which the NFL champion WAS NOT crowned as the world champion. One year later, this feet would be repeated, as the AFL Champion Kansas City Chiefs defeated the NFL Champion Minnesota Vikings in Super Bowl IV.
The Eastern Conference was split into the Capitol and Century Divisions, and the Western Conference had the Coastal and Central Divisions. In the past, if two teams were tied for the division lead at season's end, a one-game playoff was conducted to break the tie. Starting in 1967, a tiebreaking system was implemented that started with net points in head-to-head competition, followed by the team that had less recently played in a title game. As such, only one team in a division would be the division winner, even if the won-lost record was the same.
