Sure they did, that's an unfair premise on your part. You build a defense and run first team which has won more than its share of games in the NFL and more than a few SB. The base was there if you move on.
Also, you spent all summer saying Rodgers was retiring, now all of a sudden resigning him is a good deal? Come on man! You damn well know they overpaid and overplayed their hand.
The Packers FO is a bunch of Smoe's that very well may set the franchise back after this and Yes they might strike gold as well because even a blind squirrel finds a nut once in a while.
