The San Francisco 49ers stymied 2011 NFL MVP Aaron Rodgers in Week 1, then record-setting Matthew Stafford in Week 2. This stingy, opportunistic defense is again making its mark as one of the league's best facing the top offenses and most prolific passers -- and that you can shake on. The Niners denied Stafford another milestone, Vernon Davis caught touchdown passes of 21 and 23 yards from Alex Smith, and San Francisco beat the Detroit Lions 27-19 on Sunday night in a September showdown of NFC powers that hardly lived up to its hype.
