The Bears entered week six against the undefeated New Orleans Saints, the team Marc Trestman and offensive coordinator Aaron Kromer worked for. The previous meeting between the two teams occurred in 2012, with the Saints winning 30-13. As a result, offensively, the two teams were similar conceptually. For the Bears' offense, a challenge exists in the Saints' 3-4 defense, which ranked sixth in yards allowed at 304.5 per game and fifth in points with 13.8. Additionally, Cameron Jordan and Junior Galette had four and three sacks, respectively, while seven other Saints had a combined total of 12 sacks. Also, Saints tight end Jimmy Graham, the defending NFC Player of the Month, had six touchdowns on the season, and was one touchdown away from tying Mike Ditka and Antonio Gates for the most touchdowns in the first five games by a tight end. Jeff Joniak writes that Soldier Field's Kentucky bluegrass could also serve as an advantage for the Bears, as Drew Brees was 0-4 in Chicago, but those losses occurred in December and January, when the climate was much colder. In the last three meetings in Chicago, the Saints committed a total of nine turnovers (4 in the 2006 NFC Championship game, 3 in 2007, and 2 in 2008), which Joniak considered "may be the only thing slowing down the Saints." After the Bears punted, Garrett Hartley kicked a 47-yard field goal. On the ensuing possession, Malcolm Jenkins forced Jay Cutler to fumble, and Cameron Jordan recovered the loose ball and reached the Bears' 6-yard line. After failing to score a touchdown, Hartley kicked a 19-yard field goal. In the second quarter, the Saints scored off Drew Brees' two-yard screen pass to Pierre Thomas to increase the lead to 13 points. On Chicago's next drive, the offense traveled 70 yards within eight plays, which ended in Jay Cutler's three-yard touchdown pass to Alshon Jeffery. The final score of the half was by Thomas, who caught a 25-yard pass from Brees. In the third quarter, after Hartley kicked a 36-yard field goal, the Bears traveled 71 yards to the Saints' 5-yard line. However, a penalty on Kyle Long for being an ineligible downfield player, followed by three consecutive incomplete passes forced Robbie Gould to kick a 27-yard field goal. Early in the following quarter, Chicago reached New Orleans' 25-yard line, but turned the ball over on downs after Cutler's pass to Earl Bennett on 4th and 2 was dropped. On the Saints' next drive, a neutral zone infraction penalty by Lance Briggs on 4th and 1 allowed Hartley to kick a 48-yard field goal to extend the Saints' lead to 26-10. However, the Bears attempted to rally, with Cutler throwing three consecutive passes to Jeffery, the final throw going 58 yards to the Saints' 2-yard line, where Brandon Marshall scored. Matt Fort&#233;'s two-point conversion allowed the Bears to narrow the gap to eight points, but the onside kick was recovered by the Saints. Although the Saints were forced to punt, with 21 seconds remaining, Cutler could only manage to throw a pass to Jeffery which reached the Bears' 41-yard line, as time ran out, giving the Saints the 26-18 win. The win marked the first time the Saints defeated the Bears in an away game since 2002, although that game occurred at Memorial Stadium in Champaign, Illinois. Jeffery broke the franchise record for most receiving yards in franchise history with 218, which surpassed Harlon Hill's 214 yards against the San Francisco 49ers in 1954. Meanwhile, Marshall was targeted only five times during the game (15 percent of targets on the Bears), the lowest since Marshall's arrival in Chicago; the Bears fell to 0-4 in games when Marshall's target percentage is less than 20 percent.
