Packers - Lions: Two of the top 5 offenses in the entire NFL
The NFC-N is loaded offensively with the Packers averaging 35 points per game and the Lions around 30 points per game.
Last season we had a losing record against these two (1-3) and they outscored us by an average of over 11 points per game in our losses. Our lone win over these two was in a game we scored 37 points.
If we are to take over the division this year we have to have a serious scoring machine (defense alone isn't going to stop the power offenses in the NFC-N this year). We will need more than just a "mediocre" oline to accomplish this.
