The Bears offense has a chance to be very strong, as they had a done of freaking key injuries last year, and added a bunch of tools in the offseason like a new #1 WR, which will allow their old #1 WR (whom was injured but talented) get even more open. Added a bunch of TEs and most importantly improved the OL (on paper).
The problem for the Bears is their defense seems like it might have a number rod holes still (though their offense being able to control the ball might help a lot), but also they're already seeming banged up... 2 starting OL, which might be their top 2, might miss the Packers game and I think their starting TE got banged up. So they were injury prone last year and looking like they might be again this year.
The Vikings basically won all of their close games last year... and they let a lot of pieces go via FA, releases, or trades... so they barely won those games last year, they might not be able to this year.
But the Lions had a dominant offense but we're 1-6 because they had no DBs and their defensive coordinator was playing extremely extremely aggressive for some reason, which only hurt the DBs.... at some point, some one smacked some sense into him, and he started playing conservative, and the DL kept winning their matchups without the additional aggressive style... and suddenly the DBs had help. Lions finished 8-2. (which included 5-0 in the division). Lions supposedly got some DB help but you better have good lines against the Lions. I think they'll win the division, but my large question is does the defensive coordinator go back to his old overly aggressive ways, or plays smart and just lets his talented DL win on their own while helping the back end more.
With the Packers, everyone is asking about Love, but my questions are actually more about the run game in both sides of the ball. Specifically the linemen... the Packers RBs have been amazing at maximizing what's given them, but it would seriously help if the OL was better at giving them more to work with. And the Packers pass rush has been on fire, but as we have seen in the past and Jets head coach mentioned last year, keep pounding away at them, and they don't hold up. Teams with strong OLs that can run the ball, and offensive coordinators willing to do it early and often might give the Packers hell.
