azcentral sports' Kent Somers breaks down the Cardinals' 19-13 win over the 49ers:
What did we learn?
Offense:
By my count, the Cardinals ran the ball eight times when they needed no more than 3 yards for a first down. They lost yards on five of those plays, gained zero yards on two, and scored a 1-yard touchdown on another. Work obviously needs to be done. After the game, coach Bruce Arians blamed mental errors by offensive linemen. They were so intent on completing double teams that they didn’t notice linebackers slipping through gaps.
