Offense did their job against Rodgers. 31 points. Stretches of nothingness is something that every Quarterback does.
Against the Rams, the offense started slow but did do well enough towards the end but the defense gave up 170 yards of rushing at halftime. Even Rams fans at the game (who I spoke to) said the Cowboys defense were nothing special, not like the media said they were. Regular season rankings are irrelevant if the defense allows 150 more yards and 15 more points than their average. Against the Packers, offense started slow but Mahomes starts just as slow much of the times. Most notably the most recent Super Bowl against the Niners.... did the Chiefs get beaten at halftime?
The two Niners games were a different story, tho.
