Dan Marino threw for 48 touchdown passes in his 1984 MVP season. This was the most touchdown passes ever thrown in a season by a quarterback at the time, and it remains the highest single-season touchdown pass total in NFL history. Marino also threw for 5,084 yards and had a passer rating of 108.9 in that season, leading the Miami Dolphins to a 14-2 record and a Super Bowl appearance.
