Seattle
The addition of Jimmy Graham will make the Saint's offense better -- even with the loss of Unger.
I kinda wonder if their defense is poised to take a step backwords, however, you have to still consider them the front-runners in the NFC going into next season.
Packers
With the resigning of Cobb and Bulaga the Packers return all 11 starters on offense for their league leading scoring offense.
Of those 11 players on offense, only one of them is over 30 years old in Aaron Rodgers.
They have a number of ascending offensive players including Lacy, Davonte Adams, and Corey Lindsey (center).
They fielded their best offense line in over a decade last season and it may have been the best pass blocking line the NFL. Their offensive line is young -- the oldest of them is 28.
Their defense will need to replace Tramon Williams (likely gone) but they also have an ascending player in Ha Ha Clinton Dix.
The Packers defense will continue to be the weak platoon, however, it improved significantly in the 2nd half of the season and played well enough to win against about Dallas and Seattle.
