The Dallas Cowboys defense came into Week 5 top-5 across the board, and in most cases top-3, in seemingly every metric that carries weight.
All the 49ers did was score three touchdowns in the first half — it should have been four had it not been for a fumble — and three touchdowns on their first three possessions of the second half.
Kyle Shanahan had an outstanding game-plan that kept Micah Parsons off balance. But it was the familiarity with Cowboys’ defensive coordinator Dan Quinn as well as his vanilla schemes that ultimately led to the Niners offense moving the ball at will.
