High Quality Content by WIKIPEDIA articles! The period of 1979 to 1993 was one of the most succesful 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).
