Waiting for Cardinals' offense to hit gear

Larry Fitzgerald has five receptions, Beanie Wells is averaging 3.7 yards per touch and Ryan Williams (2.2 per touch) has lost two fumbles.

Oh, and one other thing about the Arizona Cardinals: Their record is 2-0.

An award-winning, unapologetic defense has done most of the heavy lifting, with occasional assists from the offense and special teams.

The chart, from ESPN Stats & Information, shows yards per reception and rushing attempt -- yards per touch -- for the 2012 Cardinals, all other teams and for the 2011 Cardinals through two games.

In the video, I offer a few thoughts on what it means heading into the Cardinals' home game against Philadelphia in Week 3.

Cardinals coach Ken Whisenhunt was confident in his team's running game heading into the regular season. The obvious concerns were in pass protection after tackles Levi Brown and Jeremy Bridges suffered season-ending injuries.

Through two games, however, the ground game has faltered against two strong run defenses. The pass protection struggled some against Seattle in Week 1, but Arizona has taken only two sacks thus far. Twenty-six teams have taken more. Arizona has lost only five yards to sacks, the second-lowest figure in the NFL (Buffalo has not taken a sack).
