1920–1932: The early years

At its inception in , the NFL had no playoff system or championship game: the champion was the team with the best record during the season as determined by winning percentage, with ties excluded. This sometimes led to very unusual results, as teams played anywhere from six to twenty league games in a season, and not all teams played the same number of games or against league talent. As a result, in the league's first six seasons, four league titles were disputed and had to be resolved by the league's executive committee. In 1920, the
Akron Pros The Akron Pros were a professional football team that played in Akron, Ohio from 1908 to 1926. The team originated in 1908 as a semi-pro team named the Akron Indians, but later became Akron Pros in 1920 as the team set out to become a charter ...

and league management insisted the game be counted in its standings (the league, at the time, did not recognize exhibition matches). The result was that although the two teams were effectively tied in the standings, the disputed game, having been played later, was given more weight and thus ended up being considered a de facto championship game. Chicago also had one fewer tie game. A nearly identical situation recurred in

The league awarded the Cardinals the title, one of only two in the team's history, but the Cardinals declined the offer and the championship was vacated. Only in 1933, when the Bidwill family (which still owns the Cardinals) bought the team, did the Cardinals reverse their decision and claim the title as their own, a decision that continues to be disputed, with the Bidwills opposing any change in the record and the two current Pennsylvania teams in favor. The league recognized the Bidwills' claim to the title and has taken no other action on the issue, although a self-made championship trophy from the Maroons sits in the

. Ironically, it was Pottsville's win in that game against the Notre Dame All-Stars that gave professional football legitimacy over college football. Part of the controversy over these older championships stems from the criteria the league used to determine its champion. The league used a variation of ''win percentage'' as its criterion, in which the number of wins is divided by the sum of wins and losses, and ties were excluded. The league began considering ties in its standings in 1972, counting them as half a win and half a loss, but this was not applied retroactively. Had it been, it would have changed the outcome of four 1920-1931 championships: the Buffalo All-Americans would have tied the Akron Pros for the 1920 title, the Duluth Kelleys would have tied the Cleveland Bulldogs for the 1924 title, the Pottsville Maroons would have won in 1925, and the New York Giants would have won in 1930. Had win–loss differential (the standard method in baseball) been used, the Decatur Staleys would have won the 1920 title by virtue of being one game ahead of Buffalo, and the 1924 title would have been won by the Frankford Yellow Jackets, who were four games ahead of actual champion Cleveland in the standings by that measure. At the end of the season, the

and the Portsmouth Spartans were tied with the best winning percentage at .857, with the Spartans record of 6–1–4 and the Bears record of 6–1–6 taken to be six wins, one loss, while the Green Bay Packers finished 10–3–1. Had pure win–loss differential or the current (post-1972) system of counting ties as half a win, half a loss been in place in 1932, the Packers' record of 10–3–1 (.750, +7) would have won them a fourth consecutive championship, ahead of the Spartans' 6–1–4 (.727, +5) and the Bears' 6–1–6 (.692, +5). To determine the champion, the league, reportedly at the behest of George Preston Marshall, voted to hold the first official playoff game in

which forced some temporary rule changes. The game was played on a modified 80-yard dirt field, and Chicago won 9–0, winning the league championship. Since the game counted in the standings, Portsmouth finished third behind Green Bay. A number of new rule changes were instituted, many inspired by the 1932 indoor championship game: the goal posts were moved forward to the goal line, every play started from between the hash marks, and forward passes could originate from anywhere behind the line of scrimmage (instead of five yards behind). The playoff game proved so popular that the league reorganized into two divisions for the season, with the winners advancing to a scheduled championship game.


1933–1965: The advent of the postseason


1933–1965: NFL Championship Game

Starting in , the NFL decided its champion through a single postseason playoff game, called the ''NFL Championship Game''. During this period, the league divided its teams into two groups, through as '' divisions'' and from 1950 onward as ''conferences''. * Divisions (1933–1949): Eastern and Western * Conferences (1950–1952): American and National * Conferences (1953–1966): Eastern and Western * Conferences and Divisions (1967–1969): Eastern (Capitol and Century) and Western (Central and Coastal) Home field for the 1933 title game was determined by the won-lost percentage in use at the time; the Western Division champion

Thereafter, from 1934 onward, the divisions alternated the site of the playoff, with the East/American hosting in even years and the West/National in odd years. If there was a tie for first place within the conference, an extra playoff game decided who would go to the NFL Championship Game, with a coin toss deciding where the game would be played.

; the final edition was played in January 1970. Starting with the 1934 game the winning team received the Ed Thorp Memorial Trophy. The trophy was named after Ed Thorp, a noted referee, rules expert, and sporting goods dealer. Thorp died in 1934 and a large, traveling trophy was made that year, passed along from champion to champion each season with each championship team's name inscribed on it. Teams would also receive a replica trophy. The trophy was last awarded to the Green Bay Packers in 1967. Late in the 1940 season, NFL President Carl Storck announced that sudden death periods would be authorized for any playoff game needed to decide either division title. It was emphasized that this did not apply to the final championship game, which would crown co-champions in the event of a tie. While a shared championship was deemed an acceptable solution, it must have become obvious that an elimination game leading to the championship must necessarily produce a winner. Commissioner Elmer Layden approved a similar arrangement for the 1941 season, with the same limitation. A coin toss would decide possession of the Ed Thorp trophy that accompanied the league title should the championship game result in a tie. Sudden death overtime was finally approved for the NFL championship game in 1946 and has remained in effect ever since. The first playoff game requiring overtime was the

In 1949, the league held a four-team playoff, with home field based upon won-lost record. The Browns, led by Quarterback Otto Graham, won all four of the league championship games.

and NFC) at 13 teams each; each conference split into three divisions. With only six division winners in the newly merged league, the NFL designed an eight-team playoff tournament, with four clubs from each conference qualifying. Along with the three division winners in each conference, two '' wild card'' teams (one from each conference), the second-place finishers with the best records in each conference, were added to the tournament. The first round was named the "Divisional Playoffs", the winners advancing to the "Conference Championships" (AFC & NFC). Two weeks later, the AFC and NFC champions met in the

, now the league's championship game. Thus, Super Bowl V in January 1971 was the first Super Bowl played for the NFL title. With the introduction of the wild card, a rule was instituted to prohibit two teams from the same division (champion and wild card) from meeting in the first-round (Divisional Playoffs). This rule would remain in effect through the season. More significantly, the home teams in the playoffs were still decided by a yearly divisional rotation, not on regular-season records (excluding the wild-card teams, who would always play on the road). This lack of "home-field advantage" was most evident in the 1972 playoffs, when the undefeated

The institution of "home-field advantage"

In , the league modified its 1970 playoff format by instituting a seeding system. The surviving clubs with the higher seeds were made the home teams for each playoff round. The three division champions in each conference were seeded first through third based on their regular-season records, with the wild-card team in each conference as the fourth seed. Teams that earned the top seed became known as clinching "

" throughout the playoffs, since they played all of their playoff games at their home stadium (except for the Super Bowl, played at a neutral site). However, the league continued to prohibit meetings between teams from the same division in the Divisional Playoffs. Thus, there would be times when the pairing in that round would pit the first seed versus the third, and the second versus the fourth.


Further playoff expansion

The league expanded the playoffs to 10 teams in , adding a second wild-card team (a fifth seed) from each conference. The two wild-card teams from each conference (the fourth and fifth seeds) played each other in the first round, called the "Wild Card Playoffs." The division winners (the first three seeds) would then receive a '' bye'' to automatically advance to the Divisional Playoffs, which became the second round of the playoffs. In the divisional round, much like the playoff format, teams from the same division were still prohibited from playing each other, regardless of seeding. Under the format, teams from the same division could meet only in the wild-card round or the conference championship. Thus, as before, a divisional champion could only play a divisional foe in the conference championship game. A players' strike shortened the 1982 season to nine games. The league used a special 16-team playoff tournament for that year. The top eight teams from each conference qualified (ignoring the divisional races—there were no division standings, and in some cases, two teams from the same division did not play each other at all that season). The playoffs reverted to the 1978 format in the following year. In , the NFL expanded the playoffs to twelve teams by adding a third wild-card team (a sixth seed) from each conference. The restrictions on intra-division playoff games during the Divisional Playoffs were removed. However, only the top two division winners in each conference (the 1 and 2 seeds) received byes and automatically advanced to the Divisional Playoffs as host teams. The 3 seed, the division winner with the worst regular-season record in each conference, would then host the 6 seed in the Wild Card Playoffs. In , the NFL realigned into eight divisions, four per conference, to accommodate a 32nd team, the

. The playoffs remained a 12-team tournament, with four division winners (the 1, 2, 3, and 4 seeds) and two wild cards (the 5 and 6 seeds) from each conference advancing to the playoffs. Again, only the top two division winners in each conference would automatically advance to the Divisional Playoffs, while everybody else had to play in the Wild Card round. Furthermore, the league still maintains the names "Wild Card Playoffs", "Divisional Playoffs", and "Conference Championships" for the first, second, and third rounds of the playoffs, respectively. A proposal to expand the playoffs to 14 teams by adding a third wild card team (a seventh seed) from each conference, and only giving the 1 seeds the bye in the first round, was tabled by the league owners in 2013.For more information on the proposed playoff expansion visit

For the first thirteen seasons, the APFA/NFL did not hold a championship game, except in , when a playoff game was held. Played indoors on a reduced-size field, it was the precursor to the championship game (though the losing team finished in third place in the final standings). For the seasons from –, the NFL did not include tie games in the winning percentage; they were omitted from the calculation.

Undefeated regular seasons and "perfect seasons" in professional football

(*) Since the NFL did not count tied games in league standings until 1972, these seasons were considered to be "perfect" at the time they finished; further, these teams had no incentive to avoid tied games in order to maintain a "perfect" season. Thus, the accuracy of calling these seasons "imperfect" is still disputed.
