I don't know, apparently we tried for the last two off-seasons to get Richard Sherman. You would hope that with the way Xavien Howard is playing and with the promise that Lippett/Tankersley have shown that we will try to keep developing those guys, but I could definitely see Miami swinging a trade for Sherman or somebody.
On the subject of safeties, Nate Allen is still under contract, right? He actually played pretty well at FS before he got hurt. I think a lot of the team's pass coverage issues could be mitigated by going to Dime looks with McDonald, Jones, and Allen in the mix.
Jones and McDonald are strong enough in run support that it would be viable, IMO.
Allen signed a 1 year deal. He was pretty "jagish" this year but that isn't necessarily a bad thing IMO. His injury history should make him a very cheap resign and one that we probably should do if everything checks out physically.
Lamarcus Joyner is out there, but will significantly more expensive.
