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 and by T.J. Watt in 2021).
In a week 10 game against the Kansas City Chiefs, the Seattle Seahawks set numerous NFL records for interception returns, including most interception return yardage in a game and most interceptions returned for touchdowns in a game with 4 (all touchdowns over 50 yards in length). The Seahawks also tied an NFL record with 63 defensive takeaways on the season.
Salaries increased significantly over the past two seasons in the NFL, up nearly fifty percent; new Houston Oilers quarterback Warren Moon led the list at $1.1 million.[2]
February 18, 1984: The New Orleans Saints acquire quarterback Richard Todd in a trade with the New York Jets.
February 23, 1984: The Pittsburgh Steelers acquire David Woodley in a trade with the Miami Dolphins.

In an attempt to head off a bidding war within its own ranks for United States Football League and Canadian Football League players, a one-time supplemental draft of USFL and CFL players was held on June 5, 1984. This supplemental draft was especially designed for players who would have been eligible for the regular NFL draft but had already signed a contract with a USFL team after being selected in 1984 USFL Draft earlier on January 4. NFL owners did not want to risk potentially "wasting" picks in the regular draft on players who were already signed by another league, but also wanted to ensure there would not be a large influx of free agent talent in case the new rival league suddenly collapsed. With the first pick, the Tampa Bay Buccaneers selected quarterback Steve Young from BYU, who previously was selected by the Los Angeles Express with the 11th pick in the USFL Draft. Young would eventually join the Buccaneers in summer 1985 soon after the Express suspended operations.[6][7][8][9]
The penalty for a kickoff or onside kick that goes out of bounds is 5 yards from the previous spot and a re-kick must be made. However, if the second (or more) kickoff or onside kick goes out of bounds, the receiving team may choose instead to take possession of the ball at the out of bounds spot.
Leaping to try to block a field goal or an extra point is illegal unless the defensive player was lined up at the line of scrimmage.
A kicker or holder who fakes being roughed or run into by a defensive player can receive an unsportsmanlike conduct penalty.
Unsportsmanlike conduct will also be called for any prolonged, excessive, or premeditated celebration by individual players or a group of players. This is usually referred to as the "Mark Gastineau Rule" because a major reason why this change was made was to stop him from performing his signature "Sack Dance" every time after he sacked an opposing quarterback. This also referred to the Washington Redskins "Fun Bunch".
David Overstreet was killed in a car accident on June 24, 1984.[10] He was driving northbound in his 1980 Mercedes on Texas State Highway 155, when his car swerved off the road about 10 miles northeast of Tyler into gasoline pumps at a service station and exploded. [11] The Dolphins wore a helmet decal with the number 20 in his memory during their 1984 season in which they reached Super Bowl XIX.
This was the third offseason in four years in which an active Dolphins player died. Linebacker Rusty Chambers was killed in a July 1981 automobile accident, and linebacker Larry Gordon died of a heart attack while jogging in June 1983.
Ricky Bell died November 28, 1984, at the age of 29 due to complications caused by dermatomyositis. Bell was the first overall selection in the 1977 draft by the Tampa Bay Buccaneers following an All-America career at USC. Bell played for coach John McKay at USC and Tampa Bay.
Thanksgiving: Two games were played on Thursday, November 22, featuring Green Bay at Detroit and New England at Dallas, with Detroit and Dallas winning.
September 30, 1984: The Colts won their first game ever at Indianapolis during a Week 5 contest against AFC East opponent, the Buffalo Bills, winning by a 31–17 margin.
For the only time in NFL history, two teams – the Oilers and the Bills – begin the season 0–10.[12]
The Oilers defeated the Chiefs in week 11. The Bills reached 0-11 before upending the Cowboys.
Houston Oilers: Hugh Campbell was hired as head coach. Ed Biles was fired after the team lost their first six games the previous season, with defensive coordinator Chuck Studley taking over as the interim head coach.
Indianapolis Colts: Frank Kush resigned after the team went 4–11. Offensive line coach Hal Hunter served as interim for the team's final regular season game.
New England Patriots: Ron Meyer was fired after eight games, despite a 5–3 record, due to his team-wide alienation of players. Raymond Berry, who had been out of coaching since serving as New England's receivers coach from 1978 to 1981, was named has Meyer's replacement.
The Chicago Bears permanently added "GSH" to the left sleeve of the jerseys, in memory of longtime owner and coach George Halas. The Bears also added navy blue pants to wear with their white jerseys, in addition to white socks to match the white jersey's sleeve coloring.
The Cleveland Browns added new striping patterns to their brown and white jerseys, and white pants. Outlines were also added to the numbers. During the preseason, the numbers on the brown jerseys were orange trimmed with white; however, complaints about the numbers being too difficult to read prompted the color scheme to be reversed for the regular season. They also stopped using orange pants and instead wore white pants with both the brown and white jerseys. Brown-topped socks were worn with the brown jerseys, and orange-topped socks were worn with the white jerseys.
The Detroit Lions switched from gray to blue face masks.
The Green Bay Packers added player numbers to their pants at the hip, similar to the Dallas Cowboys, also adding a small gold stripe on the inner white stripe of the pants. The "TV numbers" on the jerseys were moved from the sleeves to the shoulders, and the "G" monogram on the helmets was superimposed on the jersey sleeves.
The New England Patriots made major changes to their jerseys, reinstating the "UCLA stripes" around the shoulders (last seen in 1968), replacing the two stripes at the bottom of the sleeves which were used from 1973 to 1983. The Patriots also returned to wearing red pants with their white jerseys as they did in 1979 and '80. These uniforms remained largely unchanged through 1992, except for a change to red facemasks in 1991 and the discontinuation of the red pants in 1988 and '89.
The San Diego Chargers modified the lightning bolt scheme on the yellow pants by adding a blue panel surrounding the white lightning bolt.
This was the third year under the league's five-year broadcast contracts with ABC, CBS, and NBC to televise Monday Night Football, the NFC package, and the AFC package, respectively. Howard Cosell left MNF, primarily due to the fallout of his offhand remarks about wide receiver Alvin Garrett during a 1983 broadcast that was viewed as racially insensitive. O. J. Simpson was then promoted from fill-in to full-time color commentator, joining Frank Gifford and Don Meredith in the booth. On NBC's pregame show NFL '84, Bob Costas replaced Len Berman as host. This was the last season that Phyllis George served on The NFL Today.[14]
