Document 7: History of the National Football League: The National Football League (NFL) was founded in 1920 as the American Professional Football Association (APFA) with ten teams from four states, all of whom existed in some form as participants of regional leagues in their respective territories; it took on its current name in 1922. The NFL was the first professional football league to successfully establish a nationwide presence, after several decades of failed attempts. Only two teams currently in the NFL, the Decatur Staleys (now the Chicago Bears) and the Chicago Cardinals (now the Arizona Cardinals), are founding members. The Green Bay Packers, founded 1919 (joined the NFL in 1921), is the oldest NFL franchise in continuous operation with the same name in the same location.
Document 8: U.S. history of alcohol minimum purchase age by state: From 1976 to 1983, several states voluntarily raised their purchase ages to 19 (or, less commonly, 20 or 21), in part to combat drunk driving fatalities. In 1984, Congress passed the National Minimum Drinking Age Act, which required states to raise their ages for purchase and public possession to 21 by October 1986 or lose 10% of their federal highway funds. By mid-1988, all 50 states and the District of Columbia had raised their purchase ages to 21 (but not Puerto Rico, Guam, or the Virgin Islands, see Additional Notes below). South Dakota and Wyoming were the final two states to comply with the age 21 mandate. The current drinking age of 21 remains a point of contention among many Americans, because of it being higher than the age of majority (18 in most states) and higher than the drinking ages of most other countries. The National Minimum Drinking Age Act is also seen as a congressional sidestep of the tenth amendment. Although debates have not been highly publicized, a few states have proposed legislation to lower their drinking age, while Guam has raised its drinking age to 21 in July 2010.

Document 15: List of Green Bay Packers stadiums: As of 2016, the current home of the Green Bay Packers is Lambeau Field, a 81,435 seating capacity stadium in Green Bay, Wisconsin. By the 1950s, City Stadium was seen by the NFL as too small and outdated to host an NFL team. After threats of forcing the team to move to Milwaukee, the City of Green Bay built New City Stadium, which was funded by a voter - approved bond issue, in 1957. In April 1956, Green Bay voters responded by approving (70.3%) a bond issue to finance the new stadium. After the Packers founder, Curly Lambeau, died in 1965, the stadium was renamed to Lambeau Field. Its original capacity was 32,500 seats, although it was continually expanded from 1961 to 1995 to a capacity of 60,890 seats. The stadium was farther renovated from 2001 to 2003 to a capacity of 72,515, while also updating various aspects of the stadium. The south endzone was expanded in 2013 and the Lambeau Atrium entrance was completed in 2015. These renovations increased the stadium's capacity to 81,435, making it the third largest football stadium in America. It has been continuously ranked as providing one of the best game time experiences for fans in the NFL. As of 2016, it is also the oldest continually operating NFL stadium, with the Packers having completed their 59th season. Only the Boston Red Sox at Fenway Park and the Chicago Cubs at Wrigley Field have longer active home - field tenures in American professional sports.
