IMO... The need for another quality safety outweighs the need for another corner... not that adding a veteran corner would hurt.. not at all.
In our addition at safety.. IMO, we need a guy the has just as much upstairs in the reading and COMMUNICATING with the rest of the secondary.. too many times we seen breakdowns in communication of whom has what responsibility than a pro team should..
For as much of a talented guy that Collins is.. I don't think the above is his strong suit... same with Bigby.
That being said.. would I like a talent like Robinson on the Packers.. hell yes.. but can we really afford that much payroll on corners.. remember Williams need to be secured for the long term sooner or later.
