What it means for the Cowboys: With this embarrassment, the Cowboys now find themselves chasing the Philadelphia Eagles, and they need to win intervening games versus Green Bay and at Washington to make sure the Week 17 meeting at AT&T Stadium is for the NFC East title.
If they can, they will be in their third straight de facto NFC East title game to close the season. If they can't, owner and general manager Jerry Jones will have to reassess his statement that Jason Garrett will be the coach in 2014.
It's December, so the Cowboys struggle because that's what they do. Tony Romo has taken the brunt of the criticism for that record, but Monday's loss falls squarely on the defense. Josh McCown threw for four touchdowns and ran for another score. Wide receivers Alshon Jeffery and Brandon Marshall did whatever they wanted against whomever they wanted. Matt Forte ran for more than 100 yards.
If there was ever a sign that Monte Kiffin should be out as coordinator after this season, it was this game. It's one thing to get lit up by Peyton Manning and Drew Brees. It's quite another to have it happen against a backup quarterback, even if McCown had been playing well in Jay Cutler's absence.
Stock watch: DeMarcus Ware, falling. Last week, Ware said the strength had finally returned to the quadriceps that kept him out for three games. But he was invisible versus the Bears before he was gifted a sack in the fourth quarter. Ware has two sacks since his return but is likely to see his streak of having at least 10 sacks in a season end at seven.
There's no defense in Dallas: Blame the injuries all you want, but Rob Ryan at least had an injury-riddled defense competitive last year. Kiffin has had to deal with injuries, but he had zero answers for the Bears.
The Cowboys allowed 24 points in Monday's first half. Only New Orleans and Denver had more against the Cowboys in an opening half (28 each). The Cowboys allowed 32 first downs. Only New Orleans (an NFL-record 40) and Denver (34) had more. The Cowboys allowed 498 yards. Only San Diego (506), Denver (517), Detroit (623) and New Orleans (625) had more. It's the fourth time a quarterback has had four touchdown passes against the Cowboys.
In the first half, the Bears had 12 plays of at least 10 yards. They scored quickly (a 37-second drive) and they ate up clock (90 yards, 8:10).
They did whatever they wanted to do.
Hurt again: Sean Lee made his return to the lineup after a two-game absence because of a hamstring injury but he could not finish the game after suffering a neck injury with 12:33 left in the third quarter.
Lee returned briefly for five plays before he went to the locker room for the rest of the game. Lee has yet to play a full season in his career because of injuries. He is the best playmaker on the defense, but even with him the defense has not been close to adequate. Imagine how bad things would be if Lee missed even more playing time?
The Cowboys might be about to find out.
Hey, a running game: Let's get about the only positive the Cowboys had from Monday's game: They ran the ball well. DeMarco Murray ran for 145 yards on 18 carries. He now has 842 on the year and has a shot at reaching 1,000 for the season.
But why be positive on a night like this?
What's next: The Cowboys return to AT&T Stadium on Sunday to face the Green Bay Packers. The biggest question is whether Aaron Rodgers will make his return from a collarbone injury. If he does, the task is much more difficult. The Cowboys are 5-1 at AT&T Stadium this season, but the Packers have some good memories there as well, having won Super Bowl XLV there.
