That start on Sunday from the defense was absolutely the opposite of what the Cowboys had in mind against a rather toothless 49ers attack. The only way the 49ers get to 21 would have to be by some gift from the visitors, and perhaps that was given in the form of the Cowboys looking rather asleep early.
Maybe it was the tempo getting on them quick. But, for whatever reason, the Chip Kelly-designed offense looked like Thanksgiving 2014 again as they marched up and down the field twice for touchdowns in the first quarter (and part of the early second).
