Let's not get too confident. The Cards were without Adrian Wilson, their version of Charles Woodson. Wilson can cover, has great instincts, and is one of the few players with the skill set to match-up against Finley well.
Warner is great against the Blitz; not as good as Favre, but still top-notch. He can hurt you, and do it in a hurry.
Fitz and Boldin are going to be tough. You can bet they'll set those guys in motion and/or play them from the slot to get match-up advantages.
DRC is a probowl corner. He has the tools to hold his own against someone like Jennings.
The Cards are a talented team. You have to credit the Packers, but you can't discredit the Cards; they return much the same starters that came within seconds of winning the Superbowl last year.
