The regulars (Dashon Goldson, Carlos Rogers, Donte Whitner) picked up right where they left off the 2011 season: great coverage and big hits.
But it was the emergence of Tarell Brown and Chris Culliver that really caught my eye. Both youngsters played fantastic games. They combined for 12 tackles and two tipped passes.
You look at the numbers Rodgers put up against this unit, and it's pretty disheartening. Then you take into account that it was Aaron freakin' Rodgers, and it looks pretty darn good. He has no limit to the number of receiving weapons to spread the ball to, yet the 49ers' secondary held him to an un-Rodgers-esque 93.3 QB rating.
Rogers had a big sack, and the array of blitzes used on defense was creating some much needed havoc. Even though the Packers QB put up over 300 yards on nearly 70 percent completions, it seemed like he was mostly throwing short outs and slants to pick up yardage.
The deep ball was mostly taken away by the secondary, and if they could hold Rodgers to a performance like this, I'm confident that nobody will be able to throw on this unit.
That being said, there were some times that the coverage was a little soft, and though I had no reason to be really worried, the ease with which Rodgers hit James Jones over and over again on the final Green Bay scoring drive was frustrating.
By the way, the newest secondary addition to this group, Perrish Cox? He didn't have a great debut, missing tackles like it was the fall fashion.
