The Green Bay Packers’ 55-14 rout of the Chicago Bears wasn’t another shutout, but ratingswise the blowout was the worst the NBC show has done this TV season. In metered market results, last night’s game at Lambeau Filed got an 11.1/18. But honestly, what do you expect when the team from a major market like Chicago was down 42-0 at halftime? That’s the largest halftime deficit ever for an NFL game in primetime. Even a minor late rally wasn’t going to really overcome that.

The previous SNF MM ratings low was 11.4/18 on October 26, when Green Bay lost 44-23 to the New Orleans Saints. It should be noted that the Packers-Saints matchup was head-to-head with Game 5 of the World Series on Fox. On a Sunday night of non-sports competition, the bottom for SNF was October 12, when the Philadelphia Eagles thrashed the NY Giants 27-0. That game, which faced the record-breaking and demo-winning Season 5 debut of AMC’s The Walking Dead, got a 6.0/16 result in fast nationals. That went up to 6.6 in final numbers.

Last night’s SNF was down 6% in MM results compared with last week, when the Pittsburgh Steelers’ 42-23 win over the Baltimore Ravens got a 6.1/16 in early numbers. That November 2 game, which also lost out to Walking Dead in the key demo, moved up to a 6.7 in the final nationals.

As we wait for more SNF ratings, here are the top 5 markets for the Packers-Bears game: Milwaukee (49.2/68), Chicago (26.3/38), Las Vegas (19.7/30), Minneapolis (15.5/24), and Sacramento (13.2/21).
