Looking at FA CB's out there pretty thin. Only ones who you would at this point would sign to more than one year deals would be Gaines and Cockrell and also perhaps Breeland if you feel that his foot issue is a non-issue and he will be fine.
Outside of that a few guys you consider to bring in on 1 year deals would be House who knows the system, DRC who is starting to slow down but might have one more good year in him. Bryon Maxwell and Jermey Lane two players who have had lots of injury issues but can be decent if they could stay healthy. Also Tramon Williams. He is old at 35 but played decent for the Cardinals last year and has been in Pettine's D before.
So 8 players listed there who would you want?
