Cardinals Notebook: O-line struggles lead to preseason shuffling

Here are some Cardinals links from various outlets covering the team.

• The Cardinals are experimenting with D’Anthony Batiste at right tackle and Jeremy Bridges at right guard. They’re also leaving the tackles on their own against pass rushers to see what they can handle in the preseason. Kent Somers of the Arizona Republic had that and other interesting thoughts from O-line coach Russ Grimm.
  
  
• Is the Cardinals defense a little too impressed with itself after 2011’s superb finish? Coordinator Ray Horton thinks so after a pair of subpar preseason performances, Darren Urban of azcardinals.com reported.
  
  
• For the past eight months, the question has been: Kevin Kolb or John Skelton? Here’s another to ponder: What if neither Cardinals quarterback is good enough to be an NFL starter? What if both are nothing more than backup quality?
  
  
• Here another take on the Cards QB quandary from Jim Corbett of USA Today.
