The 1967 NFL season was the 48th regular season of the National Football League. The league expanded to 16 teams with the addition of the New Orleans Saints. The league's teams were realigned into four divisions: the Capitol (Dallas, New Orleans, Philadelphia and Washington) and Century (Cleveland, New York, Pittsburgh and St. Louis) Divisions in the Eastern Conference, and the Central (Chicago, Detroit, Green Bay and Minnesota) and Coastal (Atlanta, Baltimore, Los Angeles and San Francisco) Divisions in the Western Conference. The Saints and the New York Giants agreed to switch divisions in 1968 and return to the 1967 alignment in 1969.
The Baltimore Colts had tied for the NFL's best record at 11–1–2, but were excluded from the four team playoff, because of the rules for breaking ties within a division. The L.A. Rams won their division title over Baltimore as a result of the Rams' 34–10 win over Baltimore on the last game of the regular season and a 24–24 tie against Baltimore earlier. In competition against Baltimore, L.A. had a 1–0–1 edge, giving them the tiebreaker. Each of the other three division winners had only nine victories.
The "slingshot" or "tuning fork" goalpost, with one curved support from the ground and offset behind the crossbar, was made standard in the NFL. This replaced the previous year's offset goalpost, which had two non-curved supports from the ground. Before the introduction of the offset goalpost, the supports were directly on the goal line.
A 6-foot-wide (1.8 m) border around the field was also made standard in the league. Its outer edge designates the closest that non-participants can be to the field, and thus enables the game officials to have a running lane to work in.
The Eastern Conference was split into the Capitol and Century Divisions, and the Western Conference had the Coastal and Central Divisions. (Each of the new division names began with the letter C and contained seven letters.) Under the new system, each team would play six division games (a home-and-away series against teams in its division); a game against each of the other four teams in its conference; and a nonconference game against each member of another four-team division, for a total of 14 games. 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 which team that had less recently been in a title game. As such, only one team in a division would be the division winner, even if the won-loss record was the same.
Los Angeles won the Coastal Division based on better point differential in head-to-head games (net 24 points) vs. Baltimore. The Rams and Colts played to a 24–24 tie in Baltimore in October before the Rams won 34–10 on the season's final Sunday at the Los Angeles Memorial Coliseum. NOTE: The result would be the same under the modern tiebreaker, which relies first on head-to-head record (Los Angeles won the head-to-head series, 1–0–1).
