Most of the press coverage surrounding the Arizona Cardinals the last two weeks has focused on Kurt Warner, and undoubtedly his performance will be critical to how successful the Cardinals are in today’s game.

If Warner on Sunday is as accurate throwing the ball and as effective at quick decision-making as he’s been in Arizona’s last four games, it may be difficult for the Pittsburgh Steelers to keep the ball out of the hands of Larry Fitzgerald and Anquan Boldin.

That may be especially true of Fitzgerald, who, with Warner’s help, has already accumulated more yards in a single postseason than any receiver since the NFL-AFL merger.

Most Postseason Receiving Yards, Single Season – Since 1970

Larry Fitzgerald, 2008 Ari. . . 419
Jerry Rice, 1988 SF. . . . . . . 409
Steve Smith, 2003 Car. . . . . .404
Charlie Brown, 1983 Was. . . .401
Anthony Carter, 1987 Min. . .391

With Warner at his best in recent weeks, Fitzgerald has been nearly impossible to defend. Boldin, who made some noise two weeks ago with a sideline confrontation with offensive coordinator Todd Haley and by skipping the team’s postgame celebration, is an equally dangerous threat who averages more receptions and receiving yards per game than anyone in the history of the league who has played at least 50 regular-season games.

Arizona RB Edgerrin James has shown an ability to find daylight against Pittsburgh, averaging 79.8 yards per game and nearly four yards a carry in three career appearances against the reigning AFC champions. It will go a long way for Arizona if James can find some running room and keep the Steelers honest on the defensive side. That could only help Warner, who is riding the crest of a performance surge that began in November 2007.

When he’s at his best, Warner has been unbeatable, whether it’s 1999 or 2008. And for the Arizona Cardinals, who have been beatable for more than 60 years, the spot-on quarterback and his dangerous wideout threats should make for a super surprise on Sunday.
