Document 3: New York Brickley Giants: The New York Giants (informally known as Brickley's Giants and Brickley's New York Giants) were a professional American football team with the American Professional Football Association (now the National Football League) whose only season played was in 1921. The team has also been referred to as the Brooklyn Giants and Brickley's Brooklyn Giants. The Brickley's Giants were the first of 17 professional football teams to represent New York City at one time or another. The team was founded in 1919 by Charles Brickley, who received All-American honors while at Harvard. Brickley's Giants played two games in their only season, losing to the Buffalo All-Americans, 55–0, and the Cleveland Tigers, 17–0. It was the second-shortest-lived franchise in NFL history, behind only the Tonawanda Kardex, who played only one game in the same 1921 season.
Document 4: Brooklyn Dodgers (NFL): The Brooklyn Dodgers were an American football team that played in the National Football League from 1930 to 1943, and in 1944 as the Brooklyn Tigers. The team played its home games at Ebbets Field of the baseball National League's team, the Brooklyn Dodgers. In 1945, because of financial difficulties and the increasing scarcity of major league-level players because of the war-time defense requirements at the height of World War II, the team was merged with the Boston Yanks and were known as the Yanks for that season. This old NFL franchise was not related to the earlier (second incarnation) American Football League II with a franchise that played as the Brooklyn Tigers for the first half of the 1936 season before moving to Rochester, New York and playing as the Rochester Tigers. Another NFL team that played in the Brooklyn borough was the Brooklyn Lions (which became the Brooklyn Horsemen after merging with a team from an earlier first incarnation AFL of the same name) in 1926. Later co-owner and partner Dan Topping (1912–1974), pulled the Tigers team out of the old NFL in 1946 and placed it in the newly established rival professional league – the All-America Football Conference, which shortly lasted until 1949 until several stronger teams from the AAFC merged with and entered a reorganized NFL in 1950. It lasted until 1970 with the NFL-AFL (third) merger following the establishment of the first "Super Bowl" inter-league national championship game three years before with the old NFL champions playing the victors of the latest rival fourth incarnation of the American Football League IV, formed in 1960 (now the American Football Conference (AFC).
Document 5: Kentucky Colonels: The Kentucky Colonels were a member of the American Basketball Association for all of the league's nine years. The name is derived from the historic Kentucky colonels. The Colonels won the most games and had the highest winning percentage of any franchise in the league's history, but the team did not join the NBA in the 1976 ABA–NBA merger. The downtown Louisville Convention Center (now known as The Gardens) was the Colonels' original venue for the first three seasons before moving to Freedom Hall for the remaining seasons, beginning with the 1970–71 schedule.
Document 6: Evansville Crimson Giants: The Evansville Crimson Giants were a professional American football team based in Evansville, Indiana and were a part of the National Football League in 1921 and 1922. The Giants home games were played at Bosse Field. According to the "Evansville Courier and Press" in 1921, 'they surprised local fans in developing a winning team' and 'the Giants' one-sided victories over inferior non-league teams has had good fan reaction.' However, the team did not succeed, mostly due to scheduling mistakes and management problems. Evansville's local sporting enthusiasts also failed to respond favorably and attend the home games.
Document 7: Oorang Indians: The Oorang Indians were a traveling team in the National Football League from LaRue, Ohio (near Marion). The franchise was a novelty team put together by Walter Lingo to market his Oorang dog kennels. All of the Indians players were Native American, with Jim Thorpe serving as its leading player and coach. The team played in the National Football League in 1922 and 1923. Of the 20 games they played over two seasons, only one was played at "home" in nearby Marion. With a population well under a thousand people, LaRue remains the smallest town ever to have been the home of an NFL franchise, or probably any professional team in any league in the United States.
Document 8: Louisville (NFL): Louisville, Kentucky had two professional American football teams in the National Football League: the Louisville Breckenridges (or Brecks for short) from 1921 to 1924 and the Louisville Colonels in 1926.
Document 9: 1922 NFL season: The 1922 NFL season was the third regular season of what was now called the National Football League (NFL); the league changed their name from American Professional Football Association (APFA) on June 24. The NFL fielded 18 teams during the season, including new league teams such as the Milwaukee Badgers, the Oorang Indians, the Racine Legion, and the Toledo Maroons. Meanwhile, the Chicago Staleys changed their name to the Chicago Bears, and the Racine Cardinals changed their name to the Chicago Cardinals. The Muncie Flyers, Cleveland Indians, Brickley's New York Giants, Cincinnati Celts, Tonawanda Kardex, Washington Senators, and Detroit Tigers dropped out of the league. A 19th team, the Youngstown Patricians, was scheduled to join the league, and had its schedule laid out, but folded before playing in the league. A 20th, the Philadelphia Union Quakers, also was set to join (but presumably not as far along as the Youngstown plans), but did not, due partly to the fact that the Quakers were merely a front for the existing Buffalo All-Americans to play extra games on Saturday. After a four-year hiatus, the Quakers instead joined the American Football League (1926).
Document 10: Falls City Brewing Company: Falls City Brewing Company was based in Louisville, Kentucky, USA. The company operated from 1905 until 1978. After the company closed the Falls City brand was purchased by a group of investors who sold it in the late 1990s to the Pittsburgh Brewing Company who produced the brand until around 2007.

They had a record of 2 wins, 5 losses and 1 tie. The team played its home games at Chicago's Wrigley Field (then called Cubs Park) and was the first NFL team to do so. The Tigers were never formally members of the APFA. However, since the team played seven games against APFA teams in 1920, resulting in a 1–5–1 league record, they are generally included in the league standings.
Document 14: Denver Broncos: The Denver Broncos are an American football team based in Denver, Colorado. The Broncos compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) West division. The team began play in 1960 as a charter member of the American Football League (AFL) and joined the NFL as part of the merger in 1970. The Broncos are owned by the Pat Bowlen trust.

C. Pyle and star Red Grange (New York Yankees, Los Angeles Wildcats, and Chicago Bulls) and league champion Philadelphia Quakers. The initial lineup of teams included the traveling Wildcats and a charter member of the National Football League, the Rock Island Independents, which became a second traveling team after having poor attendance in its first three games.
