The Cardinals have one of the few offenses in the league that can match the Saints'offense in diversity.
Arizona's receiving corps is deep enough to overcome the absence of Anquan Boldin, who missed last week's playoff victory over Green Bay with knee and ankle sprains.
Boldin didn't practice Tuesday but expressed optimism about practicing this week and playing Saturday against the Saints in the divisional round.
The Cardinals are 6-1 without Boldin over the past two seasons, however. They beat the Packers last week with Steve Breaston stepping into the starting role, Early Doucet becoming the No.3 receiver and Jerheme Urban holding down the fourth spot.
Like the Saints, the Cardinals can spread the field with enough receivers to test the depth of any secondary. With Kurt Warner, the Cardinals have a quarterback who can read defenses quickly and get the ball out.
And Warner has proven to be one of the best playoff quarterbacks in history.
His post-season passer rating is 104.6, second only to Bart Starr, who had a rating of 104.8. Wanrer has 31 touchdown passes in 12 playoff games and has averaged 312.2 yards passing a game.
--QB Kurt Warner is in far better health than he was last season at this time, when his hip was ailing. Warner barely played in the season finale and was hit only twice against the Packers last week.
--QB Matt Leinart hasn't been impressive in spot duty this season, playing well only when he had a full week to prepare.
--RB Beanie Wells has become the team's featured back. He had more carries than Tim Hightower in the final half of the season and led the team in rushing with 793 yards.
--RB Tim Hightower remains the starter, even though he doesn't carry the ball as much as Beanie Wells. Hightower is an excellent receiver and blocker.
--RB Jason Wright plays a limited role when the team goes to its two-back sets in passing situations. He does catch some passes near the goal line and can play fullback in a pinch.
--RB LaRod Stephens-Howling is contributing in a minor role as a third-down back. Stephens-Howling is dangerous when matched up against safeties and linebackers.
--WR Larry Fitzgerald is reasonably healthy and has been productive on the field. He has 13 touchdown catches in the regular season and two more in the first playoff game.
--WR Anquan Boldin has a sprained left ankle and will miss practice time this week. Boldin has said he will play against New Orleans.
--WR Steve Breaston produced again last week in a starting role. Breaston caught 7 passes for 125 yards and a touchdown against Green Bay, starting in place of the injured Anquan Boldin.
--WR Early Doucet has improved greatly over the last half of the season. He caught six passes for 77 yards and two scores last week.
--TE Ben Patrick continues to be the team's most effective tight end and should be a red zone target in the playoffs.
--TE Anthony Becht is the best blocking tight end on the club, but he's not a big part of the passing game.
--K Neil Rackers has been reliable this season but missed a 34-yard attempt at the end of regulation last week against Green Bay. Rackers hasn't had many pressure kicks over the past two season.
--DE Calais Campbell has seven sacks in his first full season as a starter, but he has a fractured left thumb. He likely will be playing with a cast, which would limit his effectiveness.
--FS Antrel Rolle wore down last week after missing a week with a thigh bruise. Rolle is working this week to improve his conditioning.
