DB problem

08/17 i drafted: Pollard, Stevie Brown, Da'Norris Searcy and Matt Elam

Brown - done for the year
Searcy  - not a starter
Elam - not a starter

I already pick up Aaron Willians and drop Brown and Searcy, now i'm thinking drop Elam, but i'dont know who i add to my roster, doesn't have good free agent options.

Some of my options:

Reggie Nelson
Thomas DeCoud
T.J. McDonald
Lardarius Webb
Tyrann Mathieu

So, who do you think i should add to my team

Thanks

None of the FAs are overly exciting to me. Webb has some nice value in big play leagues, but outside of that I would probably just stick with Elam.
