Column: Ryan Poles has talked about finding value in free agency. But the Chicago Bears GM will need to make a big move or two to give QB Justin Fields a chance.

A year ago, Poles was with the Chiefs as they plotted to overhaul their offensive line. The first of many moves was signing guard Joe Thuney to a five-year, $80 million, deal. The Bears are going to need a guard if they don’t re-sign James Daniels, who will be an unrestricted free agent and could command upward of $10 million per season, and they’ll likely look to provide competition for or replace center Sam Mustipher. There is a good crop of guards and centers slated to reach free agency , plus the possibility of left tackle options such as Terron Armstead, Orlando Brown and Cam Robinson.
