Question: Jack Reynolds won his first super bowl with the niners  in which season ?
Context: The 1986 New York Giants season was one of the most successful seasons in the professional football franchise's history.  The New York Giants, who play in the National Football Conference (NFC) of the National Football League (NFL), won their fifth championship—and first Super Bowl—in franchise history during the season.  Led by consensus league Most Valuable Player (MVP) linebacker Lawrence Taylor and Super Bowl MVP quarterback Phil Simms, the Giants posted a 14–2 record during the regular season, tied for the best record in the league with the defending Super Bowl champion Chicago Bears and the best in team history.  The Giants improved on their 10–6 record from 1985, won their first division championship since the NFL-AFL merger in 1970, and won Super Bowl XXI against the Denver Broncos. Super Bowl XXXVII was an American football game between the American Football Conference (AFC) champion Oakland Raiders and the National Football Conference (NFC) champion Tampa Bay Buccaneers to decide the National Football League (NFL) champion for the 2002 season.  The Buccaneers defeated the Raiders by the score of 48–21, tied with Super Bowl XXXV for the seventh largest Super Bowl margin of victory, and winning their first ever Super Bowl.  The game, played on January 26, 2003 at Qualcomm Stadium in San Diego, California, was the sixth Super Bowl to be held a week after the conference championship games (XVII, XXV, XXVIII, XXXIV, and XXXVI).  It was also the last Super Bowl played in the month of January.  Super Bowl XXXVI was the first to be played in February, due to the NFL postponing games for a week after the September 11 attacks.  Starting with Super Bowl XXXVIII in 2004, the Super Bowl has been permanently played in February.  This was the last Super Bowl until Super Bowl 50 to take place in California. Super Bowl X was an American football game between the National Football Conference (NFC) champion Dallas Cowboys and the American Football Conference (AFC) champion Pittsburgh Steelers to decide the National Football League (NFL) champion for the 1975 season.  The Steelers defeated the Cowboys by the score of 21–17 to win their second consecutive Super Bowl.  They were the third team to win back-to-back Super Bowls.  (The Miami Dolphins won Super Bowls VII and VIII, and the Green Bay Packers won Super Bowls I and II.)  It was also the first Super Bowl in which both participating teams had previously won a Super Bowl, as the Steelers were the defending champions and the Cowboys had won Super Bowl VI. Super Bowl XXXIV was an American football game between the National Football Conference (NFC) champion St. Louis Rams (now the Los Angeles Rams) and the American Football Conference (AFC) champion Tennessee Titans to decide the National Football League (NFL) champion for the 1999 season.  The Rams defeated the Titans by the score of 23–16, capturing their first Super Bowl win and first NFL championship since 1951.  The game, played on January 30, 2000 at the Georgia Dome in Atlanta, was the fourth Super Bowl to be held a week after the conference championship games (the previous time this happened was Super Bowl XXVIII, and coincidentally that game was also played on January 30 at the Georgia Dome in Atlanta). Super Bowl VI was an American football game between the National Football Conference (NFC) champion Dallas Cowboys and the American Football Conference (AFC) champion Miami Dolphins to decide the National Football League (NFL) champion for the 1971 season.  The Cowboys defeated the Dolphins by the score of 24–3, to win their first Super Bowl.  The game was played on January 16, 1972, at Tulane Stadium in New Orleans, Louisiana, the second time the Super Bowl was played in that city.  Despite the southerly location, it was unseasonably cold at the time, with the kickoff air temperature of 39 F making this the coldest Super Bowl ever played. Super Bowl XLVIII was an American football game between the American Football Conference (AFC) champion Denver Broncos and National Football Conference (NFC) champion Seattle Seahawks to decide the National Football League (NFL) champion for the 2013 season.  The Seahawks defeated the Broncos 43–8, the largest margin of victory for an underdog and tied for the third largest point differential overall (35) in Super Bowl history with Super Bowl XXVII (1993).  It was the first time the winning team scored over 40 points, while holding their opponent to under 10.  This became the first Super Bowl victory for the Seahawks and the fifth Super Bowl loss for the Broncos, the most of any team.  The game was played on February 2, 2014, at MetLife Stadium at the Meadowlands Sports Complex in East Rutherford, New Jersey, the first Super Bowl played outdoors in a cold-weather city and the first Super Bowl to be played on a February 2. Jack "Hacksaw" Reynolds (born November 22, 1947) is an American former football player who played for the University of Tennessee, and started out as a fullback and changed to linebacker.  He was a first-round draft pick by the Los Angeles Rams in the 1970 NFL Draft and played there 11 years before going to the San Francisco 49ers in 1981.  He played with the Niners four more years and won two Super Bowls with them: Super Bowl XVI and Super Bowl XIX.  He wore the number 64 throughout his career.  He played in a total of 13 postseason games.  Reynolds currently splits his time between a house in Miami and another in the Caribbean. The National Football League playoffs for the 2010 season began on January 8, 2011.  The postseason tournament concluded with the Green Bay Packers defeating the Pittsburgh Steelers in Super Bowl XLV, 31–25, on February 6, at Cowboys Stadium in Arlington, Texas.  This was the first Super Bowl in which the NFC representative was a #6 seed, and only the second time one has made the Super Bowl (the previous being the 2005 Pittsburgh Steelers in Super Bowl XL). Super Bowl XVI was an American football game between the National Football Conference (NFC) champion San Francisco 49ers and the American Football Conference (AFC) champion Cincinnati Bengals to decide the National Football League (NFL) champion for the 1981 season.  The 49ers defeated the Bengals by the score of 26–21 to win their first Super Bowl. The Super Bowl Most Valuable Player Award, or Super Bowl MVP, is presented annually to the most valuable player of the Super Bowl, the National Football League's (NFL) championship game.  The winner is chosen by a fan vote during the game and by a panel of 16 football writers and broadcasters who vote after the game.  The media panel's ballots count for 80 percent of the vote tally, while the viewers' ballots make up the other 20 percent.  The game's viewing audience can vote on the Internet or by using cellular phones; Super Bowl XXXV, held in 2001, was the first Super Bowl with fan voting.
Answer: the 1981 season
