The Minnesota Vikings season was the franchise's 22nd season in the National Football League.
 This was Minnesota's first season in the newly constructed Hubert H. Humphrey Metrodome.
 The team was looking to improve on its 7-9 record from 1981.
 However, a players strike cancelled 7 of the team's 16 games, and each NFL team was only allowed to play 9 games.
 The Vikings would win their opener against the Tampa Bay Buccaneers before losing the next week to the Buffalo Bills, a game in which they had a 19-0 lead before the Bills pulled off a miraculous comeback to win 23-22.
 After the strike ended, the Vikings would get embarrassed in Green Bay against the Packers 26-7 before beating the Bears the next week 35-7 to sit at 2-2.
 After a loss to the Dolphins, the Vikings would win their next 2 games to sit at 4-3.
 In their final game of the season, they would upset the Dallas Cowboys 31-27 to clinch the NFC's 4th place spot in the playoffs (as divisions were ignored in 1982 and the standings were determined by conference).
 In the playoffs, the Vikings would defeat the Atlanta Falcons 30-24 to reach the divisional round.
 However, in that game, they would lose 21-7 to the eventual champion Redskins.

Charles Wade Wilson (born February 1, 1959) is an American football coach and former quarterback who played for the Minnesota Vikings, Atlanta Falcons, New Orleans Saints, Dallas Cowboys and the Oakland Raiders in a seventeen-year career from 1981 to 1998 in the National Football League (NFL).

Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia – April 29, 1998 in Los Angeles, California) was a former American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975.
 Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975.
 In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively.
 In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs.
 In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals.
 Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them.
 Cowan was replaced by Doug France in 1976.
The 1961 National Football League draft took place at the Warwick Hotel in Philadelphia on December 27–28, 1960.
 The league would later hold an expansion draft for the Minnesota Vikings expansion franchise, and the Vikings were also awarded the first selection position in this draft.
 This draft was also the first regular draft for the Dallas Cowboys as they had only participated in the 1960 NFL expansion draft that year.
 The Cowboys held the worst record in the NFL the previous season, but selected second in this draft because of the entry of the Vikings into the league.
The 1961 NFL season was the 42nd regular season of the National Football League (NFL).
 The league expanded to 14 teams with the addition of the Minnesota Vikings, after the team's owners declined to be charter members of the new American Football League.
 The schedule was also expanded from 12 games per team to 14 games per team.
 The Vikings were placed in the Western Conference, and the Dallas Cowboys were switched from the Western Conference to the Eastern.
 The addition of the Vikings returned the NFL to an even number of teams.

Wendell Edward Tucker (born September 4, 1943) is a former professional American football player who played wide receiver for four seasons for the Los Angeles Rams.
 Tucker spent most of his first season on the "taxi-squad" while learning behind the Rams' starting flanker Bernie Casey.
 Tucker saw action in 10 of the team's 14 games in 1968 (catching only 7 passes but 4 of them went for touchdowns), and then became the starting flanker after Casey's retirement.
 The 1969 season would prove to be his most productive as, playing opposite wide receiver Jack Snow, he caught 38 passes for 629 yards and 7 touchdowns, including a 93 yarder vs. the 49ers for the Coastal Division champion Rams.
 Tucker returned in 1970 but was hampered by injuries and caught only 12 passes in 12 games.
 In May 1971, Tucker was traded along with Billy Truax to the Dallas Cowboys for receiver Lance Rentzel.
 However, unable to regain his trademark speed because of a knee injury, Tucker retired before the start of the 1971 season.
