American Football Database

Throughout its history, the National Football League and other leagues have used several different formats to determine their league champion, including a period of interleague match-ups determining a true world champion.

The NFL first determined champions through end-of-season standings, but switched to a playoff system in 1933. The rival All-America Football Conference and American Football League, which have since merged with the NFL (some AAFC teams in 1950, but because of a problem with the NFL-AAFC merger, AAFC championships games and records don't count in NFL record books. The AFL begun play in 1960 and used a playoff system to determine its champions like the league it was rivaling at time of formation.

From 19661969 prior to the AFL-NFL merger in 1970, the NFL and the AFL agreed to hold an ultimate championship game, first called the AFL-NFL World Championship game and later renamed the Super Bowl after 1968. The most important factor of the merger was the fact that the all ten AFL teams joined the NFL in 1970 and every AFL championship game and record count in NFL record books. Since the merger, the NFL has become the only major professional football league in the United States. The Super Bowl was originally a game between the AFL and the NFL but after the merger, the Super Bowl was retooled as the NFL's championship game. The old NFL Championship game became the NFC Championship Game, while the old AFL Championship became the AFC Championship Game. The NFL lists the old AFL/NFL championship games with 'new' AFC/NFC championship games in its record books. In the NFL's "modern era" (since the AFL-NFL merger in 1970) the Steelers have posted the best record in the league. The franchise has won the most total games, won the most divisional titles, earned the best winning percentage (including every expansion team), earned the most All-Pro nominations, and have accumulated the most Super Bowl wins (six) since the modern game started in 1970. It is 2nd overall in playoff wins and tied with the Miami Dolphins for most regular-season wins. Since the merger, the team's playoff record is 33-19 (.635), which is second best in terms of playoff winning percentage behind the Green Bay Packers' playoff record of 28-16 (.636), through 1/23/11

1920 – 1932: The early years

For a list of NFL standings champions prior to 1933, see List of NFL end-of-season champions

At its inception in {{nfly|1mike had no playoff system or championship game. The champion was the team with the best record during the season, determined by winning percentage, with ties omitted. This sometimes led to very odd 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 went undefeated, but two teams that had won more games (and who had both tied Akron), the Buffalo All-Americans and Decatur Staleys, petitioned the league for a share of the title; both teams' petitions were denied, and Akron was awarded the first (and only) Brunswick-Balke Collender Cup. The next was in the 1921 NFL season, between the same All-Americans and Staleys (with the latter now being based in Chicago). Buffalo had insisted that the last matchup between the two was an exhibition match not to be counted toward the standings; however, Chicago owner George Halas, as well as 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 less tie game.) A nearly identical situation recurred in 1924, when Chicago tried the same tactic of a final game against the Cleveland Bulldogs, but the league ruled the opposite and declared the last game "post-season," giving the Bulldogs their third consecutive league title. The fourth and final disputed title was the 1925 NFL Championship controversy between the Pottsville Maroons and the Chicago Cardinals. The Maroons had been controversially suspended by the league at the end of the 1925 NFL season for an unauthorized game against a non-NFL team, allowing the Cardinals to throw together two fairly easy matches (one against a team consisting partly of high school players, also against league rules) to pass Pottsville in the standings. The league awarded the Cardinals the title, one of only two in the team's history, in a decision that continues to be disputed to this day, with Cardinals owners opposing any change in the record and the two current Pennsylvania teams in favor. No action has been taken by the league itself to address the issue, although a self-made championship trophy from the Maroons sits in the Pro Football Hall of Fame. Ironically, it was Pottsville's win in this game against the Notre Dame All-Stars that gave professional football legitimacy over college football.

Part of the controversy over these 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. Ties were treated as if the game had never been played. The league began considering ties in its standings in 1974, counting them as half a win and half a loss; this was not applied retroactively. Had it been, it would have changed several championships: the Buffalo All-Americans would have won a share of the 1920 title, and the Duluth Kelleys would have tied for first place in 1924. Had win-loss differential, the standard used in baseball, been used, the 1924 title would have gone to yet another team: the Frankford Yellow Jackets, who were four games ahead of eventual champion Cleveland in the standings by that measure; the Decatur Staleys would have similarly won the 1920 title by virtue of being one game ahead of Buffalo.

In the 1932 season, the Chicago Bears and the Portsmouth Spartans tied with the best regular-season winning percentages (although the Green Bay Packers had four more wins). To determine the champion, the league voted to hold the first official playoff game in Chicago at Wrigley Field. Because of severe winter conditions before the game, and fear of low turnout, the game was held indoors at Chicago Stadium 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. 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 1933 season, with the winnernj.///bv

1933 – 1966: The advent of the postseason

1933 – 1966: NFL Championship Game

For a list of NFL Championship Games and winners, see List of NFL champions

Starting in 1933, 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 1949 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 (1966–1969): Eastern (Capitol and Century) and Western (Central and Coastal)

The home team for the NFL Championship Game was determined by a yearly rotation between the conferences (or divisions), not by regular-season records. If there was a tie for first place within the conference, an extra playoff game determined which team played in the NFL Championship Game. (This occurred nine times in these 34 seasons: 1941, 1943, 1947, 1950 (both conferences), 1952, 1957, 1958, and 1965.)

This last occurred during the 1965 season, when the Green Bay Packers and Baltimore Colts tied for first place in the Western Conference at 10-3-1. Green Bay had won both its games with Baltimore during the regular season, but because no tie-breaker system was in place, a conference playoff game was held on December 26 (what was scheduled to be an off-week between the end of the regular schedule and the NFL Championship Game). The Cleveland Browns, the Eastern champion at 11-3-0, did not play that week. The championship game was then held on its originally-scheduled date, January 2, 1966 --- the first time the NFL champion was crowned in January. Green Bay won both post-season games at home, beating the injury-riddled Colts (with third-string QB Tom Matte) in overtime by a controversial field goal, and taking the title 23–12 on a very muddy field (in what turned out to be Jim Brown's final NFL game).

For the 1960 through 1969 seasons, the NFL staged an additional postseason game called the "Playoff Bowl" (aka the "Bert Bell Benefit Bowl" or the "Runner-up Bowl"). These games matched the second-place teams from the two conferences; the CBS television network advertised them as "playoff games for third place in the NFL." All ten of these consolation games were played in the Orange Bowl in Miami in January, the week after the NFL championship game. The NFL now classifies these contests as exhibition games and does not include the records, participants, or results in the official league playoff statistics. The Playoff Bowl was discontinued after the AFL-NFL merger; 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 Minnesota Vikings in 1969. The actual trophy, however, is now missing.[1]

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. [2] 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.[3]

Sudden death overtime was finally approved for the NFL championship game in 1946[4] and has remained in effect ever since.[5] [6] The first playoff game requiring overtime was the 1958 NFL Championship Game.

The 1955 and 1960 NFL championship games were played on Monday afternoons, Christmas having fallen on a Sunday in those years.

1946 – 1949: AAFC Championship Game

For a list of AAFC Championship Games and winners, see List of AAFC champions

The All-America Football Conference was created in June 1944 to compete against the NFL. Even though the league outdrew the NFL in attendance, the continuing dominance of the Cleveland Browns led to the league's downfall.

For its first three seasons, the league was divided into two divisions: Eastern and Western (1946–1948). The league had no divisions in 1949. The site of the championship game during the first three was determined just as it was in the NFL --- a divisional rotation. 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.

A tiebreaker playoff game was played in 1948 to break a tie between the Baltimore Colts and Buffalo Bills (AAFC) for the Eastern Division championship. Semifinal playoff games were held in 1949, setting up a championship final between the first-place Browns and the second-place San Francisco 49ers.

In 1948, the Browns became the first professional football team to complete an entire season undefeated and untied — 24 years before the 1972 Miami Dolphins of the NFL would accomplish the task, but this feat is not recognized by NFL record books. Unlike the AFL statistics which are treated as NFL statistics, records of the AAFC and its teams (most of which folded) are not recognized. However, individual AAFC player statistics are included in Pro Football Hall of Fame records, and the defunct conference is memorialized in the Hall.

1960 – 1966: AFL Championship Game

For a list of AFL Championship Games and winners, see List of AFL champions

With its creation in 1960, the AFL determined its champion via a single playoff game between the winners of its two divisions, the Eastern and Western. The AFL Championship games featured classics such as the 1962 double-overtime championship game between the Dallas Texans and the defending champion Houston Oilers. At the time it was the longest professional football championship game ever played. Also in 1963, an Eastern Division playoff was needed to determine the division winner between the Boston Patriots and Buffalo Bills.

In 1966, the success of the rival AFL, the spectre of the NFL's losing more stars to the AFL, and concern over a costly "bidding war" for players precipitated by the NFL's Giants' signing of Pete Gogolak, who was under contract to the AFL's Buffalo Bills, led the two leagues to discuss a merger. Pivotal to this was approval by Congress of a law (PL 89-800) that would waive jeopardy to anti-trust statutes for the merged leagues. The major point of the testimony given by the leagues to obtain the law was that if the merger were permitted, "Professional football operations will be preserved in the 23 cities and 25 stadiums where such operations are presently being conducted." The merger was announced on June 8, 1966, and became fully effective in 1970.

After expanding to enfranchise the New Orleans Saints in 1967, the NFL split its 16 teams into two conferences with two divisions each: the Capitol and Century Divisions in the Eastern Conference, and the Coastal and Central Divisions in the Western Conference. The playoff format was expanded from a single championship game to a four-team tournament, with the four divisional champions participating. The two division winners in each conference met in the "Conference Championships," with the winners advancing to the NFL Championship Game. Again, the home team for each playoff game was determined by a yearly divisional or conference rotation.

The AFL on the other hand, raised its total franchise number to nine in 1966 with the Miami Dolphins, joining the Eastern Division and a tenth team, the Cincinnati Bengals in 1968. The league kept using the one-game-playoff format except when division tie-breakers were needed. With the addition of the Bengals to the Western Division in 1969, the AFL adopted a four-team playoff to determine its champion.

Following the NFL and AFL Championship Games for the 1966 through 1969 seasons, the NFL champion played the AFL champion in Super Bowls I through IV, the only true inter-league championship games in the history of professional football. The first two of these games were known as the AFL-NFL World Championship Game, as the title Super Bowl was not chosen until 1968. Thus the third AFL-NFL matchup was dubbed "Super Bowl III" and the first two matches were retronamed as Super Bowls I and II. The first two games were convincingly won by the NFL's Packers, the last two by the AFL's New York Jets and Kansas City Chiefs, leaving the leagues even at 2-2 in "World Championship" competition when they subsequently merged.

All participants in those four AFL-NFL championship games were either AFL champions or NFL champions in the record books, no matter the outcome of the Super Bowl. Three of the four league champions who lost one of the first four Super Bowls would eventually win at least one. The exception is the Minnesota Vikings which went to three others and lost all of them.

1970 – present: The Super Bowl era

For a complete list of post-merger Super Bowl winners, see List of Super Bowl champions.

Post Merger

After the 1969 season and Super Bowl IV, the AFL and NFL fully merged and underwent a re-alignment for the 1970 season. Three of the pre-merger NFL teams were transferred to the AFC (Browns, Colts, and Steelers) to level the conferences (AFC and NFC) at 13 teams each; each conference split into three divisions. Since there was now only one league, the Super Bowl became a league championship and the winner is the NFL champion.

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 Super Bowl, 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 1989 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 Miami Dolphins played the AFC Championship Game against the Pittsburgh Steelers, who had recorded three losses during the regular season, at Three Rivers Stadium in Pittsburgh.

Beginning in 1972, tie games were included in the computing of each team's winning percentage. Each tie was then counted as half of a win and half of a loss, rather than being omitted from the computation. In the past the NFL used to disregard any tie games played when they computed the standings, basing it on win/loss percentage with any ties thrown out and ignored. There were no overtime games played during the regular season.

The institution of "home-field advantage"

In 1975, 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 "home-field advantage" 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. This system is identical to that now in use by Major League Baseball.

Further playoff expansion

The league expanded the playoffs to 10 teams in 1978, 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 1970 playoff format, teams from the same division were still prohibited from playing each other, regardless of seeding. Under the 1978 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 2 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 1990, 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 2002, the NFL realigned into eight divisions, four per conference, to accommodate a 32nd team, the Houston Texans. 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 2003.[7]

AFL Championship Game and NFL Championship Game (1966–1969)

(In 1966, NFL and AFL agreed to merge and play an ultimate championship game between the two leagues entitled NFL-AFL World Championship game. The merger however didn't formally take place until 1970, because of this the NFL-AFL championship games unofficially became an additional qualifying round in the playoffs as there was still one more game to play in the season for the winner of the AFL-NFL championship games. Officially these games were still main championship in both leagues but with creation of NFL-AFL World Championship game that eventually would be known as Super Bowl. Inclusion of these eight AFL-NFL Championship games is problematical in overall listing of Most World Championships/league championships, therefore they are generally not included in the overall records.[11][12][13][14][15][16]

After the merger the AFL-NFL Championship games were replaced/retooled as/with AFC Championship game and NFC Championship game.'

(*)*Because the NFL did not count tied games in league standings until 1972 (when ties were added to past standings retroactively), these seasons were considered to be "perfect" at the time they finished. Because the rules existing at the times of those championships did not give the teams involved any incentive to avoid tie games in order to maintain a "perfect" season, the accuracy of calling these seasons "imperfect" is still disputed.

Number of Championships by franchise (1920-present)

On this list, is overall counting of championships since APFA (NFL) was originally formed in 1920 and up to 1965. Its also counts the championships of its most storied rival leagues AAFC (1945–1949) and AFL (1960–1965). AFL-NFL titles from 1966-1969 are not counted since in 1966 AFL and NFL agreed to play an ultimate championship game that eventually would become known as the Super Bowl, in part of the merger deal that was finalized in 1970.
