In the playoffs the Giants, who were the top seed in the conference ahead of the Bears, defeated the San Francisco 49ers for the second consecutive year in the playoffs by a score of 49–3. They then disposed of their division rivals, the Washington Redskins, in the NFC Championship Game 17–0. In the Super Bowl, behind Simms' 88% pass completion percentage and their strong defense, the Giants overcame a 10–9 halftime deficit and scored thirty second half points while allowing only ten more and defeated the Broncos 39–20.
After making the playoffs in 1984 and 1985, the Giants entered the 1986 season as one of the favorites to win the Super Bowl. They began the season with 31–28 loss to the Dallas Cowboys, before winning five consecutive games. After losing 17–12 to the Seattle Seahawks in week seven, the Giants won their final nine regular season games. Following the regular season, coach Bill Parcells won the NFL Coach of the Year Award, and eight Giants were named to the Pro Bowl. The Giants' defense, nicknamed the Big Blue Wrecking Crew, finished second in the league in points and yards allowed.
The 1986 Giants had been ranked as one of the greatest NFL teams of all time by fans, and members of the media. It was this Giants team that popularized the practice of the "Gatorade shower", which entailed the players dousing members of the coaching staff with Gatorade near the end of a victorious game.
