ST. LOUIS -- One defender slipped, two others whiffed and Zach Miller had clear sailing into the end zone, unusual for a tight end.
Jeremy Langford found some wide-open spaces, too, for a Chicago Bears offense that hit a high note against one of the NFL's better defenses.
Miller caught two touchdown passes, including an 87-yard score that was Chicago's longest play since 2010, and Langford also had two TDs, leading the Bears to a 37-13 victory over the St. Louis Rams on Sunday.
The Bears (4-5) improved to 3-1 on the road. They brought thousands of fans to the Edward Jones Dome, which had a season-best 58,663 tickets distributed, about 8,000 shy of capacity.
Langford was untouched on an 83-yard TD on a screen and also had a 6-yard scoring run. The running back, filling in for the injured Matt Forte, had seven catches for 109 yards and 73 yards on 20 carries.
Todd Gurley had a 6-yard scoring run on the opening drive for the Rams (4-5), who have lost two straight since entering November with a winning record for the first time since 2006. Their defense entered ranked fifth overall.
Jay Cutler added a 26-yard scramble, the quarterback's longest since 2009, for Chicago. He could have had had more had he not made a safety-first slide in the third quarter.
Gurley was bottled up, rushing for 45 yards on 12 carries with a long of 9 yards, and led St. Louis with three catches for 44 yards.
Wes Welker had three catches for 32 yards, one for a first down, in his 2015 debut six days after signing with St. Louis. The Rams were 4 for 14 on third down, slightly improved from 4 for 37 the previous three games.
Linebacker Akeem Ayers slipped in coverage on Miller's long touchdown. Miler split two defenders and also outran cornerback Trumaine Johnson on his 87-yard score. He had totaled 58 yards receiving on five catches for an 11.6-yard average the first eight games.
Langford, a fourth-round pick who started for the second straight game in place of Forte, had 73 yards on 20 carries and 109 yards on seven receptions.
The Rams found lots of space on their opening 80-yard drive, which featured passes of 29 yards to Jared Cook and 1 yards to Gurley, setting up Gurley's 6-yard scoring run. They mustered 205 yards the rest of the way.
