The 1985 Bears' defense ranked first in the league and only allowed 198 total points (an average of 12.4 points per game). The Bears won the NFC Central Division by seven games over the second-place Green Bay Packers and earned the NFC's top seed and home-field advantage throughout the playoffs at Soldier Field. In their two playoff games against the New York Giants and Los Angeles Rams, the Bears outscored their opponents 45–0 and became the first team to record back-to-back playoff shutouts.
The Bears won their first twelve games of the season before losing to the Miami Dolphins on Monday Night Football. The loss to the Dolphins would be the only loss the Bears would suffer that season, as they finished with a 15–1 record.
The defense led the league in points allowed (198), yards allowed (4,135) and takeaways (54), a feat that wouldn't be accomplished again until the 2013 Seattle Seahawks defense.
