In 1984, the Dolphins won their first 11 games en route to a 14–2 season (the franchise's best 16-game season to date). Marino, in his first full season, produced one of the most impressive set of passing statistics in NFL history, setting single-season records for most yards (5,084), touchdown passes (48), and completions (362). He was voted NFL MVP . Miami avenged the Seahawks loss from the previous year 31–10 and crushed the Steelers 45–28 in the AFC Championship to advance to Super Bowl XIX. In the title game, however, Miami lost to the San Francisco 49ers 38–16. It would be Marino's only Super Bowl appearance.
