Honestly for all our our division, I'd say attack their OLs hard and heavy!
The Bears OL, especially that right side is clearly their weakness. Stop their run game and their passing game can't do it alone even with an improved QB... though with how mobile their 1st round pick might be, could make that tougher, but they seem to want to keep him on the bench at least to start the season.
The Lions lack deep threat weapons after losing muliple FA WRs and their new staff focusing so much on linesmen, which when they develop might be tough... but for now, they're not well enough rounded and they already stated their game plans to out muscle and out will other teams, which is especially true because they don't have the WRs to help too much.
As for Vikings, I think the article is wrong, yes the CBs we're a weakness last year but they signed Patrick Peterson, Bashaud Breeland and Mackensie Alexander to help CB. That's three potential decent starting CBs and starting S Xavier Woods. Also two starting DTs. Honestly, I'm not sure the Vikings defense has a weakness right now... or if they do it's their edge rushers. A lot might depend if DE Hunter is healthy or not.
But the Vikings team weakness has to be their pass protection combined with the inconsistent of their starting QB gets rattled.
You still have to stop the Vikings run attack first which is easier said than done, but if you can and then get some great licks on the QB, that offense can fall apart.
I see the division as a two way race between Packers and Vikings. Of course, I could be underrating the Bears and Lions, but while I think the Lions are going the right direction, I'm not sure they have enough tools. And Bears have a major hole on the right side of their OL, with a new QB and a play caller whom too often forgets to run the ball... even when that the strength of the offense at times.
