I'm goin with the Cards for a few reasons.

1. They have Larry Fitzgerald(not to mention Boldin). Who I believe is far and away the best WR in the NFL right now and I think Boldin is in the top 5.

2. They are the underdog, probably by a pretty good spread, anybody remember last year?

3. Kurt Warner has been here before...several times.

and finally, 4. Their D has been playing pretty well in the playoffs and I don't think the Steelers O is as good as people give them credit for.
