What's Going On Chicago?

The New Orleans Saints embarrass the Bears, who were Brees-less, Kamara-less, and Cook-less.  Nagy feels you don't need to run the ball to win games and says a change has to happen.  Will it happen?  Does the defense need Vic Fangio back as they have struggled the last two weeks?  The offense is one of the worst in the league and the defense can't slow down any team.  The only question remains, what changes will happen to get the Bears back on track?
