Niners quarterback Trent Dilfer vs. Cardinals pass defense. The most amazing part of Rolle's performance against the Bengals is that he is a nickel back who had only two career interceptions before playing the Bengals. The Cardinals are crediting the defensive schemes of defensive backs coach Teryl Austin to their recent success, which includes six interceptions in the past two games. The Cardinals will face a 49ers team that has struggled passing the ball with Alex Smith, who is out at least two weeks, and Dilfer. Teams don't respect San Francisco's aerial attack and are successfully focusing their attention on running back Frank Gore, who has struggled breaking free from all of the extra attention.
