They've beaten the (other) toughest defense in the NFL, so now they're going against the Arizona Cardinals. Um, yeah, you read that right. The Arizona Cardinals. No, THE Arizona Cardinals. Yes, the football franchise. Yes, Kurt Warner's Arizona Cardinals.
How the HELL are the Cardinals in the Super Bowl?
To someone who only looked at the standings in Week 8, it may seem like a league wide "We are Marshall" type accident has slain half of the NFC, and only the Cardinals are left intact. But no, like Leonidas in 300, they stabbed the Atlanta Falcons through the neck with their spear, yanked it free and threw it through the chest of the Carolina Panthers, and then used their sword to decapitate the Philadelphia Eagles.
Just keep in mind that Leonidas eventually fell. As will Arizona.
