The 2015 Denver Broncos relied on their defense to win 12 regular-season games, earn the No. 1 seed in the AFC playoffs and win three more postseason games en route to the franchise's third Lombardi Trophy. Their victory in Super Bowl 50 -- which featured seven sacks, four interceptions and only 10 points scored by the Carolina Panthers -- evoked memories of some of the best championship-winning defenses of the past 30 years.
The 1985 Chicago Bears are always the first team that comes to mind when recalling the best defenses of all time. The 2000 Baltimore Ravens had a very similar unit from a statistical standpoint. How do those dominant defenses stack up against those of recent years, specifically the 2013 Seattle Seahawks and this year's Broncos?
We will rank these teams 1-4 in five major stat categories: yards against per game, points against per game, shutouts, turnovers and defensive scores. Playoff games are included: The 85 Bears, 13 Seahawks and 15 Broncos each played of 19 games, while the 00 Ravens played a total of 20.
