Rookie Nate Potter moves up depth chart

Unable to get anything going offensively of late, the Arizona Cardinals have shaken up their offensive line heading into Sunday's game at Atlanta, with rookie Nate Potter atop the depth chart at left tackle.

The news was reported on Cardinals beat writer Darren Urban's Twitter feed on Tuesday afternoon and should hardly come as a surprise to anyone who has followed the team closely. Arizona has lost five games in a row and hasn't won since Sept. 30 against Miami.

For Potter, the news isn't totally surprising, given that the rookie was once projected to be a first-round draft pick during his college career. But after struggling as a senior at Boise State, he fell to Arizona in the seventh round of last year's draft and has been battling his way up the depth chart since then. With Levi Brown injured and backup D'Anthony Batiste struggling, Potter will be firmly entrenched as the starter Sunday.

Potter will be entering the Cardinals' lineup at a time when the offense is struggling as much as ever. In the midst of its five-game losing streak, Arizona has averaged just 10.6 points per game.
