The Cincinnati Bengals don't often think outside the box when it comes to improving their roster by any means possible. They usually take a reactive, not proactive stance to such personnel decisions.
Credit where it's due: When Joe Burrow got injured earlier this season, they waited a while, but ultimately pulled the trigger on a Joe Flacco trade. Before suffering a sprained AC joint in his throwing shoulder, and even for a brief bit thereafter, Flacco played some of the best ball of his career.
Obviously, it didn't mean much, since Cincinnati's defense kept letting him down.
