GM Ryan Poles has already done a lot to help the Chicago Bears fortify what was a top-heavy defensive line. He added edge rusher Darrell Taylor and defensive tackle Chris Williams through two trades. They should deepen the Bears’ rotation, easing the burden on starters like Montez Sweat and Gervon Dexter. One would think Poles feels comfortable about where things are at. There is no reason to stay aggressive. However, the GM has repeatedly said he will never pass on opportunities to improve his football team.
