On December 17, 1984, Miami Dolphins quarterback Dan Marino set two NFL records by throwing his 48th touchdown of the season and became the first quarterback to accumulate 5,000 passing yards in a 28-21 victory over the Dallas Cowboys.
Mark Clayton gave the Dolphins the edge when he made the fourth quarter, 63 yard reception to give Marino his 48th touchdown pass of the season. The touchdown reception gave Clayton his 18th of the season, a record at the time.
Clayton scored the first touchdown on a 41 yard pass in the second quarter from Marino, giving the Dolphins a 7-0 lead going into half time.
Bruce Hardy caught a three yard pass from Marino in the third quarter, putting the Dolphins up 14-0. Timmy Newsome got the Cowboys on the board with a one yard rush before the quarter was over.
Newsome was first to score in the fourth quarter with a four yard rush and with a field goal by Rafael Septien, the score was tied at 14.
Clayton caught a 39 yard pass, thrown by Marino, giving the Dolphins a seven point advantage. The Cowboys caught up when Tony Hill caught a 66 yard pass from Danny White. Marino’s 48th touchdown pass was received by Clayton and won the final game of the regular season for the Dolphins.
The Dolphins finished the regular season with a 14-2 record. They took the division with a 31-10 victory over the Seattle Seahawks. The Conference Championship was against the Pittsburgh Steelers and the Dolphins walked away with a 45-28 win. The San Francisco 49ers beat the Dolphins 38-16 in the Super Bowl.
The single season record for touchdown passes is 55, held by Peyton Manning, set in 2013. Manning originally broke Marino’s record in 2004 with 49. Tom Brady claimed it in 2007 with 50.
Marino finished the 1984 season with 5,084 passing yards. Five other quarterbacks have thrown over 5,000 yards in a season. Matthew Stafford had 5,038 in 2011. Drew Brees accumulated 5,069 in 2008, 5,476 in 2011, 5,177 in 2012 and 5,162 in 2013. Tom Brady had 5,235 in 2011. Peyton Manning currently stands on top of the pile with 5,477 passing yards in 2013.
