The period of 1979 to 1993 was one of the most successful in New York Giants franchise history. Members of the NFL's National Football Conference, the Giants struggled after reaching the NFL Championship Game in 1963. The 1964 season began a 15-year stretch in which the Giants were unable to make the playoffs. However, in 1979 they started rebuilding, hiring General Manager George Young, the first GM in the family-run team's history. Young, a former Baltimore Colts and Miami Dolphins executive, assembled a team that would become successful in the 1980s and early 1990s. Led by a run-oriented offense and a defense nicknamed the "Big Blue Wrecking Crew", the team qualified for the postseason six times in 10 seasons from 1981 to 1990. During that period, they won Super Bowl XXI (1987) and Super Bowl XXV (1991).

The period encompasses the careers of quarterback Phil Simms and linebacker Lawrence Taylor, two of the most accomplished players in team history. Simms was drafted to little fanfare from tiny Morehead State University in 1979, and struggled in his initial seasons before becoming a Pro Bowl quarterback. Taylor was the second selection in the 1981 NFL draft and, in contrast to Simms, was an immediate success, winning the league's Defensive Player of the Year Award in both his rookie and sophomore season. The team's success in this period was aided by head coach Bill Parcells, running back Joe Morris, and Hall of Fame linebacker Harry Carson. Following the 1990 season and a victory in Super Bowl XXV, Parcells resigned as coach and was replaced by the team's offensive coordinator, Ray Handley.

Handley served as coach for two mediocre seasons (1991–92), in which the Giants went from Super Bowl champions to a 6–10 record. He was fired following the 1992 season and replaced by former Denver Broncos coach Dan Reeves. In the early 1990s, Simms and Taylor played out the last years of their career with steadily declining production. In 1993, however, the Giants experienced a resurgent season with Reeves at the helm, and Simms and Taylor ended their careers as members of a winning team.

Building a champion: 1979–1985

The Giants made the decision to hire a general manager for the first time in team history following the 1978 season.Anderson, Dave. Sports of the Times; Ten Giant Steps to Superdom, The New York Times, January 25, 1987, accessed July 19, 2016. However, disagreements during the search caused severe friction and discord between owners Wellington and Tim Mara. At one point they had tried to hire Jan Van Duser, a league executive, but he declined the offer due to the ownership squabbles. Finally, the Maras asked NFL Commissioner Pete Rozelle to step in with a recommendation. Rozelle recommended George Young,Goldberg, Hank. Giants owner Wellington Mara dies at age 89, USA Today, October 25, 2005, accessed July 19, 2016.*Pervin. pg. 73 who worked in personnel for the Miami Dolphins and had been an assistant coach for the Baltimore Colts. Rozelle had discussed the hiring before hand with former Giants Frank Gifford and Tom Scott, who recommended hiring Young. They had already recommended Young to Wellington and his son John, but felt if Rozelle presented the recommendation as his own idea the brothers would be more likely to accept the pick. Young was hired and he was instrumental in turning around the fortunes of the franchise. "Oh, there is no question he helped save the franchise", John Mara later said. "It looked like a no-win situation. He came in and overhauled everything we did in a more professional way."Waldstein, David. New York Teams Listen to Leagues When Hiring, The New York Times, October 14, 2010, accessed July 19, 2016. Despite the hiring and subsequent success, the rift between Wellington and Tim lasted for several yearsBelichick Press Conference , patriots.com, October 26, 2005, accessed March 21, 2007. and, at one point a partition had to be put between the two in the owner's box.Burke, Monte.

Simms and Taylor arrive: 1979–1982

One of Young's first actions was to hire Ray Perkins as head coach. Perkins was an offensive assistant coach on the Dallas Cowboys under Hall of Fame coach Tom Landry.Pervin. pg. 74 In his first draft, Young drafted quarterback Phil Simms from Morehead State University with the seventh overall draft pick to the surprise of many.Katz, Michael. Giants Defend 'Value' in Choice of Simms; Perkins Optimistic Giants Selections, The New York Times, May 5, 1979, accessed March 20, 2007. Simms had never played on a winning team at Morehead State, and acknowledged after he was drafted that "[m]ost people have never heard of me." Young was certain of the choice though saying, "[o]nce in a while you get a chance to get a guy with a great arm and great potential and you'd darn sight better take it." Simms was unhappy with the selection, and had other teams which he favored playing on over the Giants.Whittingham. pg. 41 The Giants lost their first five games of the season with Joe Pisarcik starting at quarterback. Simms came on in relief of Pisarcik in the fifth game and started the next four, all of which the Giants won. They lost five out of their last seven however, finishing 6–10 for the year.Pervin. pg. 75 They fell to 4–12 in 1980.New York Giants, footballreference.com, accessed November 2, 2010. Simms play was inconsistent, as he combined for 28 touchdowns against 33 interceptions while completing 48.8% of his passes over his first two seasons.

With the second overall draft pick in the 1981 draft, the Giants selected Lawrence Taylor, linebacker out of the University of North Carolina. Taylor impressed right from the start; in training camp his teammates took to calling him Superman and jokingly suggested that his locker should be replaced with a phone booth.Whitley, David. L.T. was reckless and magnificent, espn.com, accessed January 29, 2007. The impact that Taylor had on the Giants' defense was immediate, and predicated the defense's transformation from allowing 425 points in 1980 to 257 in 1981.LT best NFL rookie of all time, espn.com, accessed July 19, 2016. He was named 1981's NFL Defensive Rookie of the Year and NFL Defensive Player of the Year by the Associated Press, becoming to date the only rookie to ever win the Defensive Player of the Year award. His arrival raised the Giants linebacker corps—which already included Brad Van Pelt and future Hall of Famer Harry Carson—into one of the league's best: the Crunch Bunch.

The Giants started the 1981 season 5–3;, databasefootball.com, accessed March 16, 2007. but lost their next three games to fall to 5–6. Further complicating matters, Simms went down with a separated shoulder in the November 15th loss to the Washington Redskins.Neft, Cohen, and Korch. pg. 724 He was replaced by Scott Brunner. However, with Brunner leading the team, the Giants beat the defending conference champion Philadelphia Eagles 20–10 before losing to the San Francisco 49ers 17–10. They defeated the Los Angeles Rams 10–7 and the St. Louis Cardinals 20–10 setting up a season finale against the Dallas Cowboys, in which a win, along with a New York Jets victory over the Green Bay Packers the next day, would clinch a playoff spot for the Giants. Wearing their white jerseys at home (so as to force the Cowboys to wear their "unlucky" blue jerseys) the Giants won the game 13–10 in overtime on a Joe Danelo field goal. The Jets defeated the Packers, clinching the Giants' their first playoff berth since 1963. The Giants defeated the Eagles on the road 27–21 in the Wild Card round for their first playoff win since 1958 and first ever road post season win, but then lost to the eventual Super Bowl champion 49ers 38–24.

The Giants were unable to build on their success in 1982, due in part to the 1982 NFL Players Strike which reduced the schedule to 9 games, and also to Ray Perkins' mid-season announcement that he was leaving the team at season's end to coach at the University of Alabama. The Giants lost their first two games before the strike and their first game upon returning. In New York's second game (against Green Bay on Monday Night Football) Carson recorded 25 tackles; 20 solo and 5 assists.Walsh. pg. 224 They then won their next three games against the Detroit Lions, the Houston Oilers, and Philadelphia to even their record at 3–3. Perkins then announced that he was leaving to coach the University of Alabama in place of the retiring Bear Bryant after the season.Litsky, Frank. Perkins to Succeed Bryant as Alabama coach, The New York Times, December 16, 1982, accessed November 29, 2010. The team's defensive coordinator, Bill Parcells, was chosen to replace him after a series of informal discussions with Young, during which Parcells did not know he was being interviewed for the position.Pepe, Phil. Giants tab Parcells as Next Head Coach, The Pittsburgh Press, December 16, 1982, accessed November 29, 2010. Parcells named Bill Belichick the team's defensive coordinator and linebackers coach before the season. Belichick would later coach the New England Patriots to six Super Bowl titles.Pervin. pg. 77 Simms, who had been unable to stabilize the quarterback situation up to that point, missed the entire season with a knee injury suffered in a preseason game against the New York Jets.Wolff, Craig. Giants Give Simms Starting Role; Carson Leaves Camp, The New York Times, August 15, 1984, accessed March 18, 2007. Young described Perkins announcement as "a setback", and said "it slowed us down, interrupted our continuity."Ziegel. pg. 82 Lawrence Taylor however, remained a bright spot, again winning the NFL Defensive Player of the Year award.

Early Parcells era: 1983–1985 Parcells first year proved difficult. In his first major decision as head coach, he decided to bench Simms in favor of Brunner based on what he had done in the 1981 season after Simms was injured. At first it appeared that Parcells' decision was justified, especially after a 27–3 victory over the Green Bay Packers gave the Giants a 2–2 record after 4 games., databasefootball.com, accessed March 16, 2007. However, the Giants collapsed from there. The team went winless in their next seven games, losing six and garnering a tie with the St. Louis Cardinals, before defeating the Philadelphia Eagles to end the streak. The Giants then lost their remaining games to finish with a 3-12-1 record, including a 1-6-1 division record and a 1-7 home record (their only win was the game against the Packers; they defeated the Eagles at Veterans Stadium and their first win came at Atlanta–Fulton County Stadium against the Falcons). Brunner had a subpar season, completing just 49.2% of his passes and throwing 9 touchdowns against 22 interceptions., databasefootball.com, accessed March 19, 2007.
