Unfortunately, the Packers have to stop the Bears on one more series due to Clay Matthews' roughing-the-passer penalty on fourth down after the play above. Having sent DBs after the QB here and there, this time Pettine sends none. All the members of the secondary stay in coverage while Martinez makes it a rather standard four-man rush, with one twist. As LBs Reggie Gilbert (93) and Nick Perry (53) criss-cross at the line of scrimmage, Martinez splits them and comes free, rushing Trubisky's throw again.

This time, on the next play, the Packers get the fourth-down stop they need to end the game.

To understand another aspect to all the variations, watch the clips again, keeping an eye on Chicago's offensive linemen. Except for play No. 3, when the Packers sent six rushers, the Bears had a member of their protection unit blocking no one while at least one defender was getting pressure. Schematically, that's a win for the defense.
