Which FA should we re-sign this year?

I'm not saying you sign one over the other.  Just that you need 3 starting quality CBs along with 2 starting safeties.  And if we do not sign Callahan, we have a huge hole.  Just like if we don't resign Amos.  It is not an either/or situation in my mind.  IMO we need both (or an equivalent quality replacement).

I wouldn't say it's a huge hole. The front 7 is strong and the LB's have the ability to cover or at least assist in coverage in most ways that would make it tough on teams.

I'm not saying ignore the position, i do see your side, but surely there are options that will allow them to get similar talent within the price tag they want or can afford.  So they can get both, but i'd have to side with paytonisgod in the fact the the safety sees more snaps, thus making it slightly more important priority to keep under contract. 

And i mainly think this way cus i've never heard of the top Nickle Back in the draft going in the top 10, let alone the 1st Rd. I just feel that a Nickle is easier to replace.

I've seen other tweets saying the market for both is kind of soft, so its plausible they stay w/the Bears.
