What it means: The Cardinals are going to have to grind, even against weak teams. That was the case for them against St. Louis in the season opener. It was the case for them against Oakland in the Cardinals' home opener, a 24-23 victory. But the Cardinals are 2-1 and the other teams in the division have issues. Arizona might be able to grind its way to a division title at this rate.
Big Revelation: Beanie Wells' knee surgery must not have been very serious. Wells was the Cardinals' most effective runner and arguably their most impressive skill-position player in this game. Wells has 14 carries for 75 yards. Look for him to become a bigger part of the offense.
Lucky stars The Cardinals are 2-1 because the Raiders' Sebastian Janikowski missed a 32-yard try in the final seconds. Janikowski also missed from 41 yards.
Receivers on radar: Derek Anerson was again erratic at times, but his scoring passes to Larry Fitzgerald and Steve Breaston gave the Cardinals a chance. Fitzgerald had a tough matchup against Nnamdi Asomugha.
What's next: The Cardinals visit the San Diego Chargers in Week 4 before facing New Orleans at University of Phoenix Stadium the following week.
