According to NFL reporter Adam Caplan's Twitter feed, the Eagles have been continuing their search for a viable fifth cornerback in the wake of Dimitri Patterson's constant injuries:
#Eagles had former #Lions 7th rounder in 2007 CB Ramzee Robinson for a workout this week.
#Eagles tried to claim CB Jack Williams so it's obvious that they are looking for some depth there.
Of course, there's always a chance current practice squad denizen Jack Ikegwuonu could make a move to the active roster, but the lengthy search so far by the Eagles suggests otherwise. Interestingly though, both Robinson and Williams have failed to make the Detroit Lions' active roster (Williams is currently on the practice squad), which should tell you something about how desperate the Birds have become for a fifth cornerback who can actually stay on the field. I wonder how long it will be before we give Trae Williams a call?
