The NFL likes to have high-scoring games especially during its nationally televised games. The league probably is going to be disappointed when this one finishes because it has the makings of a low-scoring contest. 
The Bears entered this Week 7 ranked in the bottom-six in scoring, rushing and yards per play. So why are they 5-1? Their defense has given up a league-low 4 TD passes. 
Jared Goff has had more trouble versus the Bears than any opponent. Goff has a 0-to-5 touchdown-to-interception ratio and a passer rating of 33.9 in two career matchups versus Chicago. Goff actually has played better on the road this season where nine of his 10 TD passes have occurred. 
The Rams have held four of their six opponents below 20 points. Aaron Donald entered this week leading the NFL in sacks with 7 1/2. He's going to be a load for a mediocre Bears offensive line. Nick Foles has regressed to being more game manager than gunslinger. 
So this game figures to be conservative. The teams have met the past two seasons and there was not more than 24 points scored in either one.
