"The Chicago Bears have a big offseason ahead and plenty of decisions to be made. One of the big ones is highlighted in the backfield as the Bears could lose both Adrian Amos and Bryce Callahan. We've already seen reports that Amos plans to join Vic Fangio in Denver, which would mean the Bears could make a push to keep Callahan. However according to ESPN, Callahan will likely walk too. "Slot corners have become more valuable in today's NFL, and they will remain so with pass-heavy teams in the NFC North such as the Packers and Vikings. Callahan has put in four seasons with the Bears after signing as an undrafted rookie, so they know what they have in him.Prediction: While Chicago would like to keep him, the bet here is an offer will come that's too much to stomach."With Landon Collins and Eric Weddle set to hit free agency, if Amos doesn't run for Denver, the Bears could afford to re-sign him at a reasonable price.
