‘The Buffalo defense wasn’t altogether outstanding, but it was plenty good when it needed to be. Witness Kawika Mitchell’s interception that drove a stake into the Chargers during a fourth-quarter surge into the red zone. Mitchell also defensed a pass and applied quarterback pressure on that drive, and he ended San Diego’s final drive with a strip-sack. Bear in mind that the Bills’ defense played without starting corner Terrence McGee and former Pro Bowl defensive end Aaron Schobel. Last year, Buffalo learned to play through injuries. It paid off Sunday.’
