The Miami Dolphins are a professional American football team based in the Miami metropolitan area. The Dolphins are a member of the American Football Conference (AFC) East division in the National Football League (NFL). The Dolphins play their home games at Sun Life Stadium in the northern suburb of Miami Gardens, and have their headquarters in Davie, Florida. The Dolphins and the Atlanta Falcons (who also began play in 1966) are the oldest NFL franchises in the Deep South, and Miami is the oldest AFC team in that region. The Dolphins team was founded by attorney/politician Joe Robbie and actor/comedian Danny Thomas. They began play in the American Football League in 1966. The region had not had a professional football team since the days of the Miami Seahawks, who played in the All-America Football Conference in 1946 before becoming the first incarnation of the Baltimore Colts. For the first few years the Dolphins full-time training camp and practice facilities were at Saint Andrew's School, a private boys boarding prep school in Boca Raton. In 1970 the Dolphins joined the NFL when the AFL–NFL merger occurred. The team made its first Super Bowl appearance in Super Bowl VI, but lost to the Dallas Cowboys 24–3. In 1972, the Dolphins completed the NFL's only perfect season culminating in a Super Bowl win, winning all 14 of its regular-season games, both of its NFL playoff games, and also Super Bowl VII. The Dolphins thus became the first NFL team to accomplish a perfect regular season. The Dolphins also won Super Bowl VIII, becoming the first team to appear in three consecutive Super Bowls, and the second team (the first AFL/AFC team) to win back-to-back championships. Miami also appeared in Super Bowl XVII and Super Bowl XIX, losing both games. For most of their early history, the Dolphins were coached by Don Shula, the most successful head coach in professional football history in terms of total games won. His Dolphins teams posted losing records in only two of his 26 seasons as the head coach. During the period spanning 1983 to the end of 1999, quarterback Dan Marino became one of the most prolific passers in NFL history, breaking numerous league passing records. He led the Dolphins to five division titles, 10 playoff appearances, and Super Bowl XIX before retiring following the 1999 season.

The San Francisco 49ers are an American football franchise located in the San Francisco Bay Area, that plays in the West Division of the National Football Conference (NFC) in the National Football League (NFL). The team was founded in 1946 as a charter member of the All-America Football Conference (AAFC) and joined the NFL in 1949 after the two leagues merged. The team plays its home games at Levi's Stadium in Santa Clara, California, beginning with the 2014 NFL season, after playing at Candlestick Park in San Francisco from 1971 to 2013. The original home of the 49ers, Kezar Stadium, is within Golden Gate Park in San Francisco. The 49ers are known for having one of the NFL's greatest dynasties, winning five Super Bowl championships in just 14 years, between 1981 and 1994, with four of those championships in the 1980s. The Super Bowl teams were led by Hall of Famers Joe Montana, Jerry Rice, Ronnie Lott, Steve Young, and coach Bill Walsh. With five Super Bowl wins, the 49ers are tied with rivals Dallas Cowboys for the second most Super Bowl wins. The 49ers won the most regular season NFL games in both the 1980s (104) and 1990s (113). The name "49ers" comes from the name given to the gold prospectors who arrived in Northern California around 1849 during the California Gold Rush. The name was suggested to reflect the voyagers who had rushed the West for gold. It is the only name the team has ever had and the team has always been within the San Francisco Bay Area. The team is legally and corporately registered as the San Francisco Forty Niners, Ltd., and is the oldest major professional sports team in California. The 49ers and Los Angeles Rams were cross-state rivals until 1995, when the Rams moved from Southern California to St. Louis, Missouri to become the current St. Louis Rams.
