NFL Media Senior Analyst Gil Brandt ranked the five best defenses of all-time and the 1986 New York Giants placed 5th behind the 2013 Seattle Seahawks, 2015 Denver Broncos, 2000 Baltimore Ravens, and 1985 Chicago Bears. The 2015 New York Giants defense was among the worst in the league. The 2016 New York Giants are determined to fix that and get back to greatness through free agency and the draft. But, who were the top 10 New York Giants defenses since that all-time top unit in 1986? Would you believe that the 1986 Giants were actually the second best Giants defense over the past thirty seasons?
