Marino was the first draft pick in the history of the United States Football League, selected by the Los Angeles Express. He did not sign with the team, choosing instead to sign with the Dolphins. After starting the season as a backup to incumbent starter David Woodley, Marino was given his first NFL start in Week 6 versus the Buffalo Bills. Marino and Miami lost that game 38–35 in overtime. As a rookie, Marino set several records: he posted a 96.0 passer rating, he was selected to the Pro Bowl as a rookie, he had the lowest percentage of passes intercepted with 2.03, he was the only rookie quarterback to lead a conference in passing, and he had the highest passing completion percentage with 58.45. The Dolphins finished the season with a 12–4 record and advanced to the AFC divisional playoffs, where Marino threw two touchdown passes in his playoff debut. However, he also threw two interceptions as the team lost to the 9–7 Seattle Seahawks, 27–20.
