I think if history has taught us anything it's that you can't overlook teams like the 2005 Steelers and the 2007 Giants. And the 2008 Cardinals fit perfectly into those Cinderella slippers. If the Steelers get by them, they're the Champs - 'nuff said. No crying or regrets here.
IMO, Warner is a very dangerous threat to the Steelers - he won't be in awe of the stage or rattled in any way by their defense. He makes good, quick decisions. The Cards must IMO attack Woodley and Harrison with their running game in order to slow down the pass rush. As we witnessed in this year's Pats matchup, the Steelers CAN be run on with some success.
The Cards have magically conjured a run defense during the playoffs. The area I think they can be attacked, as we witnessed in the Philly game, is through the air. Containing Miller and Holmes I think will be crucial if the Cards are to win this game.
If you think about it, the cards (pun intended) really couldn't have been dealt better for the Red Birds - two home games, and two (relatively) warm weather away games....perhaps destiny awaits?
