John Skelton is expected to start his third consecutive game on Sunday, but he likely will need to improve greatly if the Cardinals are going to beat the 49ers.
Skelton threw for three touchdowns against the Eagles last week, but he also had two interceptions that cost the team 10 points.
At least two other throws could have been intercepted. For most of the second and third quarters, the Cardinals couldn't escape awful field position because they couldn't gain enough first downs.
An improved defense was the reason for the win.
Skelton, however, did do enough to show that he has a future in the NFL. He's big, 6-6 and 244 pounds, has a strong arm and a quick release. He is mobile for a big man.
Most important, he appears to have the mental makeup to succeed. He didn't go into the tank after his mistakes, and he made great throws afterward.
Kevin Kolb likely will miss another game with his foot injury. Kolb practiced on a limited basis this week, but his participation appeared to be restricted to individual drills.
Kolb's problem is that he suffered three injuries to the foot: turf toe, a mid-foot sprain and a bone bruise on the outside of the foot.
If he didn't have the bone bruise, he could compensate better for the turf toe. If he didn't have turf toe, he could take more pressure off the side of his foot.
It appears he's at least a week away from returning. If the Cardinals beat the 49ers, however, coach Ken Whisenhunt will face a difficult decision about which quarterback to start.
"If it's a problem, then it's a good problem to have," Whisenhunt said. "It means John did his job. We've done a lot of things better, which is what we needed to do."
