Arizona and Pittsburgh will play a historic Super Bowl in Tampa in two weeks: a team with a history as bad as any in the NFL against one that will try to win a record sixth title.

Pittsburgh opens as a 6 1/2-point favorite.

That's fine with the Cardinals, who have been laughingstocks forever and won all three playoff games as underdogs, including yesterday 32-25 thumping of the Philadelphia Eagles for the NFC title.

Arizona hasn't won a title since the NFL championship in 1947 and has had only 10 postseason games since meandering from Chicago to St. Louis and finally to the desert 21 seasons ago.

Still, it is impossible to write them off, mainly because of their 37-year-old quarterback, Kurt Warner, who owns two MVP awards and was the Super Bowl MVP with the Rams in 2000.

"I want to say Arizona Cardinals and Super Bowl in the same sentence," a jubilant Warner said. "The Arizona Cardinals in the Super Bowl. How about it?"

Then there is Larry Fitzgerald, who used to practice in the same facility as the Steelers when he played at Pitt. In just three games, he has emerged as the best receiver ever in the postseason — with 419 yards, he broke the great Jerry Rice's record with the final game still to come.

"He's been here before," Fitzgerald said, referring to Warner. "He's been where we're all trying to go. He's held that trophy up and we've leaned on him this whole postseason."

Many of Pittsburgh's stars have been through this before, including Hines Ward, the MVP of the 2006 Super Bowl win over Seattle.

The Steelers' defense carried them past Baltimore, 23-14, in the AFC title game. That's what it's been doing all season. The latest version of the storied Steel Curtain was the best statistically in the NFL and the most consistent.

Led by James Harrison, the defensive player of the year and another all-Pro, safety Troy Polamalu, it puts constant pressure on the quarterback. And that is where Warner is sometimes vulnerable. Injuries and turnovers cost him his job in St. Louis in 2002 and 2003 before he was shuffled off to the New York Giants and then to Arizona.

The Steelers have four title victories in six years during the 1970s and their fifth three years ago. No team has ever won six.

In an odd little twist, Arizona coach Ken Whisenhunt has his roots with the Steelers, serving as offensive coordinator from 2004-2006, including the Super Bowl-winning team.

He was expected to get the Pittsburgh job when Bill Cowher stepped down two seasons ago. So was another Steelers coach, Russ Grimm, now Whisenhunt's right-hand in Arizona.

Instead, the job went to Mike Tomlin, who returns to Tampa, the city where he began his coaching career.

One other bit of cross-pollination.

In 1944, the Steelers and Cardinals were the same team — Card-Pitt, combined into one because of World War II, when there weren't enough able-bodied men to fill out both rosters.

They finished 0-10.

They will finish a lot better this season, no matter what happens in Tampa.

STEELERS FAVORED BY 6 1/2

Las Vegas oddsmakers aren't buying into the Arizona Cardinals, no matter how many times they win as underdogs this postseason.

The Pittsburgh Steelers were favored by 6 1/2 points in most sports books to win the Feb. 1 Super Bowl after beating the Baltimore Ravens yesterday to set up the showdown for the NFL title, according to Las Vegas Sports Consultants.

"Beating Baltimore is a little more impressive," oddsmaker Jason Been said.

Las Vegas Sports Consultants provides betting lines for roughly 90 percent of sports books in Nevada.

The Cardinals — 45-1 longshots to start the season and 40-1 to win it all when the playoffs started — aren't getting much respect from oddsmakers but seem to be building a last-minute fan base among bettors, said Jay Kornegay, executive director of the race and sports book at the Las Vegas Hilton.

"I'm not sure how big this bandwagon can get, but it's growing by the minute," Kornegay said. "The history of losing can really appeal to a lot of fans."

Kornegay set the Hilton's line at 7 points, meaning Steelers bettors would need their team to win by more than one touchdown.
