The 1972 NFL season was the 53rd regular season of the National Football League. The Miami Dolphins became the first (and to date the only) NFL team to finish a championship season undefeated and untied when they beat the Washington Redskins in Super Bowl VII. The Dolphins not only led the NFL in points scored, while their defense led the league in fewest points allowed, the roster also featured two running backs who gained 1,000 rushing yards in the same season. 
On July 13,Robert Irsay and Willard Keland bought the Los Angeles Rams from the estate of Dan Reeves and transferred ownership to Carroll Rosenbloom, in exchange for ownership of the Baltimore Colts.   
The 1972 NFL Draft was held from February 1 to 2, 1972 at New York City’s Essex House. With the first pick, the Buffalo Bills selected defensive end Walt Patulski from the University of Notre Dame.
Referee Jack Vest, the referee for Super Bowl II, the 1969 AFL championship game and 1971 AFC championship game, was killed in a June motorcycle accident. Chuck Heberling was promoted from line judge to fill the vacancy and kept Vest's crew intact. Heberling's line judge vacancy was filled by Red Cashion, who was promoted to referee in 1976 and worked in the league through 1996, earning assignment to Super Bowl XX and Super Bowl XXX.
From 1970 through 2002, there were three divisions (East, Central and West) in each conference. The winners of each division, and a fourth "wild card" team based on the best non-division winner, qualified for the playoffs. The tiebreaker rules were changed to start with head-to-head competition, followed by division records, common opponents records, and conference play.

A field goal (FG) is a means of scoring in gridiron football. To score a field goal, the team in possession of the ball must place kick, or drop kick, the ball through the goal, i.e., between the uprights and over the crossbar. The entire ball must pass through the vertical plane of the goal, which is the area above the crossbar and between the uprights or, if above the uprights, between their outside edges. American football requires that a field goal must only come during a play from scrimmage while Canadian football retains open field kicks and thus field goals may be scored at any time from anywhere on the field and by any player. The vast majority of field goals, in both codes, are place kicked. Drop kicked field goals were common in the early days of gridiron football but are almost never done in modern times. In most leagues, a successful field goal awards three points.
