On a defense like the New Orleans Saints, who use six defensive backs more often than three linebackers, obtaining significant talent at the cornerback position obviously should be the main priority.
The Saints recently released three-time Pro Bowl offensive guard Larry Warford which frees up about eight million dollars in cap space. The Saints could very well (and should) use that extra cash to add some depth to the cornerback position.
The Saints currently have seven cornerbacks on the roster and five of them either are an undrafted free agent or have just one year left on their contract.
