1. CB Malcolm Butler, New England (RFA)
For all the Patriots have done to consolidate their place atop the NFL in the last week, losing Butler could prove equally detrimental to those efforts. Butler visited the Saints this week, and while the Patriots have the cap room to match almost any offer, their investment in Stephon Gilmore could lead them to hesitate on allocating a high percentage of their future cap space to the cornerback position.
2. CB Morris Claiborne, Dallas
Claiborne's extensive injury history is the likely cause of the relative lack of interest in his services, but when healthy, he's an above-average cornerback who represents an upgrade for many teams.
