Barkley on Arizona's short list?

Earlier this offseason, Arizona Cardinals HC Bruce Arians indicated that if the season started with the group of QBs the team had on the roster at that time, he'd be comfortable putting Drew Stanton out there as his starter. After a drawn-out process over the weekend and into this week, the Cards added another option in veteran Carson Palmer. And based upon some of what we're hearing, they may target another product of USC in the draft.
