Super Bowl XLIII will put on display how football is being redefined in front of fans' eyes.
They were the Card-Pitts. They were so bad the rest of the league called them "The Carpets."
These days, the franchises have opposing game-time philosophies. The Cards, their offense led by former grocery-store stock boy Kurt Warner, face the Steel Curtain II defense and its wild-haired Greek Orthodox Samoan safety, Troy Polamalu.
The game will not only arc across history and put into crushing motion a mix of regular guys-turned-gridiron mavericks. It will also delve into the heart of a game that is being redefined in front of fans' eyes.
The adage that defense wins championships dies hard, but today's champions are more likely to rely on a balanced game plan built as much on offensive grit as defensive formations.
"The main story line is the dynamic offense of the Cardinals versus the defense of the Steelers and how these teams have built their squads," says Jeffrey Ohlmann, a University of Iowa researcher who does quantitative analysis of NFL teams.
