The 1930 NFL season was the 11th regular season of the National Football League. Prior to the season, Brooklyn businessmen William B. Dwyer and John C. Depler bought the Dayton Triangles, moved it, and renamed it the Brooklyn Dodgers. The Orange Tornadoes relocated to Newark and the Buffalo Bisons and the Boston Bulldogs dropped out. The Portsmouth Spartans entered as a new team.
Meanwhile, the Green Bay Packers were named the NFL champions for the second straight year after they finished the season with the best record.
Defending champion Green Bay won its first 8 games, including a 14–7 home win over the New York Giants on October 4. By Week Nine, Green Bay was at 8–0–0 and New York right behind at 10–1–0. On November 16, the Packers lost to the Cardinals 13–6, but in New York, the Giants fell to the Bears, 12–0. On November 23, a crowd of 37,000 turned out as the Packers and the Giants met at the Polo Grounds in New York. The Giants' 13–6 win in Week Eleven gave it the lead, 11–2–0 (.846) to the Packers' 8–2–0 (.800). Missed extra points had a big effect, as four days later, the Giants were beaten on Thanksgiving Day by Staten Island, 7–6, while Green Bay defeated Frankford 25–7 to retake the lead, 9–2–0 (.818) vs. New York's 11–3–0 (.785). The Giants faltered again on Sunday, November 30, when Brooklyn beat them 7–6, again on a missed point after.
The 1956 NFL season was the 37th regular season of the National Football League. CBS became the first network to televise some regular season games across the nation. Meanwhile, the league started to use a natural leather ball with white end stripes, instead of the white ball with black stripes, for night games.
The season ended when the New York Giants crushed the Chicago Bears in the NFL Championship Game, 47–7.
The Lions and the Cardinals had both finished 1955 poorly, 3–9 and 4–7–1, but both got off to fast starts in 1956. Both ended up finishing second in the Conference races.
The Chicago Cardinals got off to their best start ever, going 4–0, until the Redskins beat them 17–14 on October 28. At the midway point, they and the Giants had 5–1 records. In the Western Conference, the Detroit Lions roared to a 6–0 start. In Week Seven (November 11), the Giants pulled ahead with a 23–10 win over the Cards. In Washington, the Lions finally lost. Trapped on his own 1-yard line, Yale Lary took a safety in order to get a free kick. That, and Sam Baker's field goal, gave the Redskins an 18–10 lead to put the game out of reach, and the Lions lost 18–17. The Bears, who had dropped their opener at Baltimore, 28–21, beat Green Bay 38–14 for their sixth straight game, matching Detroit's 6–1 record.
The 1973 NFL season was the 54th regular season of the National Football League. The season featured O.J. Simpson becoming the first player to rush for 2,000 yards in one season. Buffalo moved their home games into Rich Stadium. After playing their first two home games at Yankee Stadium, the New York Giants played the rest of their home games at the Yale Bowl. The season ended with Super Bowl VIII when the Miami Dolphins repeated as league champions by defeating the Minnesota Vikings.
The 1948 NFL season was the 29th regular season of the National Football League. During the season, Halfback Fred Gehrke painted horns on the Los Angeles Rams' helmets, making the first modern helmet emblem in pro football. The last regular season game played on Wednesday until the 2012 season happened on September 22, 1948 between Detroit and Los Angeles. The season ended when the Philadelphia Eagles defeated the Chicago Cardinals in the NFL Championship Game.
The 1948 season featured the highest per-game, per-team scoring in NFL history, with the average team scoring 23.2 points per game. This record stood for 65 years until 2013.
