The San Francisco 49ers have surrendered just 20 points or more just once this season: the Niners’ 24-20 Week 3 win over the Pittsburgh Steelers.
Outside of that, the 5-0 49ers have never given up more than 17 points and have kept opponents in single-digit scoring twice this season.
Needless to say, San Francisco has ridden the back of its defense, which now ranks No. 2 in both points allowed (64) and yards given up (1,187). All those investments general manager John Lynch and Co. made on the defensive side of the ball are paying off handsomely.
