Green Bay Packers (12-4): With the addition of Cook and getting Nelson back, the Pack's offense looks to be back to vintage form. On the other side of the ball the defense looks to have a lot of depth and was a saving grace for them last season.
Minnesota Vikings (10-6): The Vikings are still a very good and young team. Zimmer looks to keep their defense tough and as for the offense Bridgewater will continue to have to manage to offense and hand the rock to Adrian Beat-a-son.
Chicago Bears (8-8): Chicago wants their defense looks to return to the Monster of the Midway to return after going to a 3-4 defense last year, and I believe they will improve. However what will hold them back is going to be the offensive side of the ball.
Detroit Lions (6-10): They were one of the hottest teams in the league in the 2nd half of the season last year, but now without Calvin Johnson, I find it hard that they can build off of that momentum.
