In the last two weeks, the Chicago Bears pass rush has been not existent. A lot of people point to the injury to Khalil Mack as being the turning point in this pass rushing bunch. That certainly did have a lot to do with it. As we saw on Sunday, Mack was a non-factor who mainly dropped back into coverage.
Of course, some of it would have to do with the opponent as well. Against the Miami Dolphins, the theme of the game was to throw quick passes in the screen game. You can see the discrepancy in passing styles by intended air yards.
