Actually their defense looked pretty solid. (with the addition of our offense looking very anemic)
It was really the penalties that killed them.
But give credit to the Niner defense, we were swarming and getting to Warner, and never really let them get into a rhythm. Our DB's were physical, and did a great job on Fitz & Boldin, though I know that Boldin wasn't @ 100%. Our defense threw their timing off, and stopping their offense was probably the bigger task than dealing with their defense.
