their championship, owing to his first official visit never having happened at the time. Twenty-five years after the championship, the surviving members of the team would be invited to the White House in 2011 by President Barack Obama, a Chicago native and Bears fan. Chicago Bears Under head coach Mike Ditka, who won the 1985 NFL Coach of the Year Award, the Bears went 15–1 in the regular season, becoming the second NFL team to win 15 regular season games, while outscoring their opponents with a staggering margin of 456–198. The Bears' defense, the "46 defense", allowed the fewest points (198), fewest total yards (4,135), and fewest rushing of any team during the regular season (1,319). They also led the league in interceptions (34) and ranked third in sacks (64). Pro Bowl quarterback Jim McMahon provided the team with a solid passing attack, throwing for 2,392 yards and 15 touchdowns, while also rushing for 252 yards and three touchdowns. Running back Walter Payton, who was then the NFL's all-time leading rusher with 14,860 yards, rushed for 1,551 yards. He also caught 49 passes for 500 yards, and scored 11 touchdowns. Linebacker Mike Singletary won the NFL Defensive Player of the Year Award by recording three sacks, three fumble recoveries, and one interception. One of the most distinguishable players on defense was rookie lineman William "The Refrigerator" Perry, who came into training camp before the season weighing over 380 pounds. However, after Bears defensive coordinator Buddy Ryan told the press that the team "wasted" their first round draft pick on him, Perry lost some weight and ended up being an effective defensive tackle, finishing the season with five sacks. He got even more attention when Ditka started putting him in the game at the fullback position during offensive plays near the opponent's goal line. During the regular season, Perry rushed for two touchdowns, caught a pass for another touchdown, and was frequently a lead blocker for Payton during goal line plays. The Bears' "46 defense" also had the following impact players: on the defensive line, Pro Bowler and future Hall of Famer Richard Dent led the NFL in sacks (17), while Pro Bowler and future Hall of Famer Dan Hampton recorded 6.5 sacks, and nose tackle Steve McMichael compiled eight. In addition to Singletary, linebacker Otis Wilson had 10.5 sacks and three interceptions, while Wilber Marshall recorded four interceptions. In the
