The Arizona Cardinals may be undefeated through four weeks of the 2012 NFL season, but their ground game has left something to be desired.
Beanie Wells is likely done for the season with a toe injury, and he wasn't producing much when healthy. Young tailback Ryan Williams made his first start in Week 4 and did not have a good day, picking up just 26 yards on 13 carries.
Despite their struggles, the Cardinals will not abandon their rushing attack. As quarterback Kevin Kolb explained to Daria Del Colliano of Arizona Sports, the team knows they need to improve, especially once the grind of the long season begins to take its toll.
"It's a big point of emphasis for us and we know that we're going to have to have it especially come later on in the season," Kolb explained. "That's a big part of the game as people start to get banged up and we get later on in the cold weather months."
Fortunately for Arizona, the schedule becomes much easier in the coming weeks. The Rams, who they'll face on Thursday Night Football, rank 26th in the NFL in terms of rushing defense. They have allowed an average of 135.3 yards on the ground through four games. The Cardinals then face the Bills and their 28th-ranked run defense in Week 6.
