At first, the Cardinals offense looks conventional.
There's one running back in the backfield, a tight end at the line and three receivers spread out wide. Then quarterback Kurt Warner starts his cadence, and chaos begins.
The running back, tight end and even the receivers shift one-by-one, motioning to Warner's every word.
Then silence.
All of a sudden, there's no running back in the backfield, no hint of a tight end at the line, and five wide receivers ready to create havoc on a defense primed to surrender a mismatch.
That's the 2005 Cardinals offense that debuted Saturday in a preseason 13-11 victory over the Dallas Cowboys before 36,787 at Sun Devil Stadium: part bedlam, part brilliant.
Their offense started slow and simplified in the first series. The most significant motion came from the entire unit trotting off the field after a three-and-out.
Then brilliance happened.
In the offense's fourth possession of the game, Warner completed 5 of 6 attempts for 84 yards, including a 31-yard touchdown to Larry Fitzgerald. When the first-team units jogged to the sidelines for good, the Cardinals led 10-0.
"We're just trying to get completions and try and (throw) the ball down the field," Warner said. "We're going to continue to get better. It's not bad for the first day and a new offense."
And for at least one series, the Cardinals showcased what their offense is capable of.
