Quarterback Kevin Kolb is expected to start on Sunday against the Cowboys after missing four games with a right foot injury.
His return is important to the Cardinals for at least a couple reasons. Kolb's replacement, John Skelton, has not played well in the last couple games, completing 18 of 42 passes with no touchdowns and five interceptions.
Most important, the Cardinals need to develop consistency on offense in order to build for 2012. That means trying to fix problems, and Kolb's inconsistency is the biggest one.
In his last three starts, Kolb completed 52.6 percent of his passes with more interceptions (five) than touchdowns (three).
He has yet to look comfortable in this system. He doesn't move around in the pocket well, and his decision-making about leaving the pocket has been questionable.
He's missed throws that he should have easily made.
Cardinals coaches aren't down on Kolb, but they also know they have much work to do.
Getting Kolb, and this offense, into a rhythm is the top priority over the last five games.
