Context: The season ended with Super Bowl XIX when the San Francisco 49ers defeated the Miami Dolphins 38–16 at Stanford Stadium in California. This was the first Super Bowl televised by ABC, who entered into the annual championship game rotation with CBS and NBC. This game marked the second shortest distance between the Super Bowl host stadium (Stanford, California) and a Super Bowl team (San Francisco 49ers). The 49ers became the first team in NFL history to win 15 games in a regular season and to win 18 in an entire season (including the postseason). Additionally, two major offensive records were set this season, with quarterback Dan Marino establishing a new single-season passing yards record with 5,084 (later broken by Drew Brees in 2011, 2012, 2013 and 2016, by Tom Brady in 2011, by Peyton Manning in 2013, by Ben Roethlisberger and Patrick Mahomes in 2018 and by Jameis Winston in 2019) and Eric Dickerson establishing a new single-season rushing yards record with 2,105. Another statistical record broken was Mark Gastineau for most sacks in a single season, with 22 (surpassed by Michael Strahan in 2001).
