The Cardinals (11-2) head to Philadelphia to play the Eagles (6-7). The debate about whether Cardinals' fans should sell tickets to the Packers' game or the Seahawks' game continues. The Cardinals are hoping to get defensive back Jerraud Powers back but they are not as optimistic about defensive lineman Frostee Rucker. Tight end Jermaine Gresham also appears iffy this week after not practicing on Wednesday. The defense needs to make stops on third down and do it without blitzing so much. But can they? The Eagles have won back-to-back games, including a stunner over the Patriots. What sort of problems do they present the Cardinals?The Cardinals have two milestones within reach: the NFC West title and the NFC's No. 2 seed with a win coupled with a Packers loss, and, the Cardinals can win 12 games in a season for the first time ever.
