The Arizona Cardinals are a professional American football team based in Glendale, Arizona. They currently are members of the West division of the National Football Conference (NFC) in the National Football League (NFL). The Cardinals were founded in 1898, and are the oldest continuously run professional sports team in the United States outside of baseball. The team was established in Chicago in 1898 and was a charter member of the NFL in 1920. Along with the Chicago Bears, the club is one of two NFL charter member franchises still in operation since the league's founding. (The Green Bay Packers were an independent team until they joined the NFL in 1921). The club then moved to St. Louis, Missouri in 1960 and played in that city through 1987 (sometimes referred to as the "Football Cardinals" and/or the "Big Red" to avoid confusion with the Major League Baseball St. Louis Cardinals). Other less commonly used nicknames were the "Gridbirds" (used only by a local newspaper columnist) or "Cardiac Cards" (used only to refer to the 1975 team). Before the 1988 NFL season, the team moved to Tempe, Arizona, a college suburb east of Phoenix, and played their home games for the next 18 years at Arizona State University's Sun Devil Stadium. In 2006, the club began playing all home games at the newly constructed University of Phoenix Stadium in the northwestern suburb of Glendale, although the team's training facility is in Tempe. The franchise has two NFL championships, both while it was based in Chicago. The first occurred in 1925, but is the subject of controversy, with supporters of the Pottsville Maroons believing that Pottsville should have gotten the title. Their second title, and the first to be received through a championship game, came in 1947, two decades before the first Super Bowl game was played. In the six-plus decades since winning the championship in 1947, the team suffered many losing seasons, and currently hold the league's longest active championship drought. They have been to the playoffs six times and have won six playoff games, three of which were victories during their run in the 2008–09 NFL Playoffs. During that season, they won their only NFC Championship Game since the 1970 AFL-NFL Merger, and reached Super Bowl XLIII. The team has also won four division titles (1974, 1975, 2008, and 2009) since their 1947–1948 NFL championship game appearances. In 2012 the Cardinals became the first NFL franchise to lose 700 games since its inception. The franchise's all-time mark at the conclusion of the 2013 season is 511–716–39. From 1988 through 2012 (except 2005, when they trained in Prescott), the Cardinals conducted their annual summer training camp at Northern Arizona University in Flagstaff. The Cardinals moved their training camp to University of Phoenix Stadium in 2013.

The Seattle Seahawks are a professional American football franchise based in Seattle, Washington. They are members of the West division of the National Football Conference (NFC) in the National Football League (NFL). The Seahawks joined the NFL in 1976 as an expansion team along with the Tampa Bay Buccaneers. The Seahawks are owned by the estate of Paul Allen, co-founder of Microsoft, and are currently coached by Mike Mcdonald. Since 2002, the Seahawks have played their home games at Lumen Field (formerly CenturyLink field), located south of downtown Seattle. The Seahawks previously played home games in the Kingdome (1976–1999) and Husky Stadium (1994, 2000–2001). The Seahawks are the only NFL franchise based in the Pacific Northwest region of North America and thus attract support from a wide geographical area, including Oregon, Montana, Idaho, and Alaska, as well as Canadian fans in British Columbia and Alberta. Seahawks fans have been referred to collectively as the "12th Man", "12th Fan", or "12s". The Seahawks' fans have twice set the Guinness World Record for the loudest crowd noise at a sporting event, first on September 15, 2013, registering 136.6 dB during a game against the San Francisco 49ers and again on December 2, 2013, during a Monday Night Football game against the New Orleans Saints, with a then record-setting 137.6 dB. Over the years the Seahawks have had some notable players on the team, including Steve Largent, Dave Brown, Jim Zorn, Dave Krieg, John Randle, Kenny Easley, Curt Warner, Joe Nash, Brian Blades, Cortez Kennedy, Joey Galloway, Walter Jones, Steve Hutchinson, Shaun Alexander, Matt Hasselbeck , Marcus Trufant and Russell Wilson. Largent, Kennedy, and Moon have been inducted into the Pro Football Hall of Fame, as was Jones in 2014. Easley, Jones, Kennedy, Krieg, Largent, Warner, and Zorn have been inducted into the Seahawks Ring of Honor, along with cornerback Dave Brown and defensive end Jacob Green. The Seahawks have won nine division titles and three conference championships. They are the only team to have played in both the AFC and NFC Championship Games. They have appeared in three Super Bowls, including Super Bowl XLVIII where they defeated the Denver Broncos 43–8 to win their first NFL title. However, the Seahawks went on to lose Super Bowl XLIX to the New England Patriots, 28–24. They are also the first, and to date only, post-merger expansion team in NFL history to advance to play in consecutive Super Bowls. As per one of the agreed parts of the 1970 AFL–NFL merger, the NFL began planning to expand from 26 to 28 teams. In June 1972, Seattle Professional Football Inc., a group of Seattle business and community leaders, announced its intention to acquire an NFL franchise for the city of Seattle. In June 1974, the NFL gave the city an expansion franchise. That December, NFL Commissioner Pete Rozelle announced the official signing of the franchise agreement by Lloyd W. Nordstrom, representing the Nordstrom family as majority partners for the consortium. In March 1975, John Thompson, former Executive Director of the NFL Management Council and a former Washington Huskies executive, was hired as the general manager of the new team. The name Seattle Seahawks ("Seahawk" is another name for Osprey) was selected on June 17, 1975 after a public naming contest which drew more than 20,000 entries and over 1,700 different names. Thompson recruited and hired Jack Patera, a Minnesota Vikings assistant coach, to be the first head coach of the Seahawks; the hiring was announced on January 3, 1976. The expansion draft was held March 30–31, 1976, with Seattle and the Tampa Bay Buccaneers alternating picks for rounds selecting unprotected players from the other 26 teams in the league. The Seahawks were awarded the 2nd overall pick in the 1976 draft, a pick they used on defensive tackle Steve Niehaus. The team took the field for the first time on August 1, 1976 in a pre-season game against the San Francisco 49ers in the then newly constructed Kingdome.
