For the rest of the 20th century, the Shula-led Dolphins emerged as one of the most dominant teams in the NFL with a strong running game and defense, with only two losing seasons between 1970 and 1999. They were extremely successful in the 1970s, completing the first complete perfect season in NFL history by finishing with a 14–0 regular season record in 1972 and winning the Super Bowl that year. It was the first of two consecutive Super Bowl wins and one of three appearances in a row. The 1980s and 1990s were also moderately successful. The early 80s teams made two Super Bowls despite losing both times, and saw the emergence of future Hall of Fame quarterback Dan Marino, who went on to break numerous NFL passing records, holding many of them until the late 2000s. After winning every game against the division rival Buffalo Bills in the 1970s, the two teams gradually developed a competitive rivalry in the 80s and 90s, often competing for AFC supremacy when Jim Kelly emerged as the quarterback for the Bills. The Dolphins have also maintained a strong rivalry with the New York Jets throughout much of their history.
