We've noted before how the Saints have managed to stay active in free agency, despite limited salary-cap room.
This one's not on the level of signing cornerback Jabari Greer or safety Darren Sharper, but the Saints added some more depth to their defensive backfield Thursday by signing veteran safety Pierson Prioleau.
That's not going to change the plan to use Sharper as the starting free safety and Roman Harper at strong safety. However, it gives the Saints another experienced backup to go with Kevin Kaesviharn, and it may keep the team from going through with the possible move of cornerback Usama Young to safety.
Prioleau gives the Saints an instant insurance policy at safety because he already knows the defense after spending last year in Jacksonville with coordinator Gregg Williams. A 10-year veteran, Prioleau also has been a regular on special teams throughout his career.
