It would be easy to get the impression that Khalil Mack is the beginning and end of the good things that are happening in Chicago. The man is impressive, and every sign indicates that he was worth both the picks given to trade for him and the contract he inked to keep him with the Bears long-term. However, while he is certainly helping the Bears both directly (by being a beast) and indirectly (by making things easier for everyone else), it’s worth looking at three other things the Bears have quietly gotten better at this year.
