The NFL season got off to a roaring start on St. Louis television last weekend, as the three contests shown on Sunday afternoon had the best combined rating for the opening slate of day games in the four seasons since the Rams bolted from St. Louis.

The Giants-Cowboys matchup, the only NFL game on local television in the late-afternoon slot, was seen in 11.1 percent of homes with a TV. That’s according to Nielsen, which tracks viewership. It was on KTVI (Channel 2).

At noon, KTVI showed Rams-Panthers and KMOV (Channel 4) carried Chiefs-Jaguars. The Chiefs’ game drew an 8.3 rating, a figure that includes about a half-hour of other contests that were shown because of technical troubles CBS had in the late stages of the Kansas City game. The Rams’ rating was 6.6, after their opener last year drew a 5.5 figure locally when it was the nightcap of the ESPN “Monday Night Football” doubleheader.

The Packers-Bears kickoff to the season, on KSDK (Channel 5), had the second-best St. Louis rating for the Thursday night opener of the post-Rams era. It drew an 11.1 figure, trailing only the 12.1 for Panthers-Broncos in 2016.

Meanwhile, NBC’s “Sunday Night Football” game, the Patriots’ rout of the Steelers, drew the lowest St. Louis figure for the opener of that package 11.0 — in the last four seasons.

Nationally, Week 1 ratings generally were similar to last year’s overall performance.
