Keep your eye on ...
Darnell Dockett's domination at the line of scrimmage: Dockett's impact is not always best measured in statistics (he has only 32 tackles and 2.5 sacks this year), but his physical play at the point of attack is a big reason why Arizona has the league's eighth-best run defense. He and his Cardinals defensive linemates will have to be at their best against St. Louis' Steven Jackson, who is third in the NFL with 915 rushing yards.
Donnie Avery's emergence: While Avery has had some decent outings this season, consistency remains an issue. He tends to follow up a solid game with a disappearing act. He was sensational against the Saints, with two touchdown catches, but his challenge will be to follow that up with another good game against the Cardinals.
