Where does Shawn Springs fit on the Eagles?

The Eagles next free agency move could be signing veteran CB Shawn Springs. Springs has been a solid corner over the years for the Redskins. Springs is visiting the Eagles. The Eagles should be able to add the experienced (12 years) 34-yeard-old CB to a low-to-moderate price. Presumably, Springs would be the 4th corner on the depth chart. The move could also assist the Eagles move Sheldon Brown to safety. A secondary of Asante Samuel, Joselio Hanson, Sheldon Brown, and Quitin Mikell would work extremely well and Springs would be a nickel corner.
