It's easy to say the Steelers, but after the Cardinals last two games, I'm not so sure they couldn't pull it off.
I'd like to see the Cards, as they're the underdog, and have had two very impressive wins to get to the S.B., but my mind is saying Pittsburgh.
Personally, my S.B. was the Cards v. the B'Eagle's.
A very good game was capped by the Cards knocking the B'Eagles out of the playoffs!
