I would gladly move on from Morris Claiborne (age 25, $5.175M cap # this year) & Brandon Carr (age 29, $12.7m cap # this year, $13.8M cap # next year) and then sign a couple of no-name free agent CB's like:
Casey Hayward 5-11/192 Green Bay (age 26, $1.05M cap # this year)
Brandon Boykin 5-10/185 Pittsburgh (age 25, $1.5M cap # this year)
Trumaine Johnson 6-2/208 St. Louis (age 25, $1.5M cap # this year)
Obviously as free agents, those 3 are going to get more $ next year, but their first year cap #'s are going to be significantly less than Claiborne's and Carr's.
Corey White is a free agent I would let walk as well. Scandrick is back next year, so him, Byron Jones, and 2 new CB's will improve the secondary. A free safety to replace Church would be a Christmas miracle.
