What happened against the Seahawks is the Packers literally didn't play the full 60 minutes. They had double digit lead with something like ~4 minutes to go and they started (figuratively) telling family members how many Super Bowl tickets they could get and before they knew it, they had to march down the field just to hope for a FG to tie the game for over time.
The Packers let themselves sit on autopilot and it came back and bit their asses off.
They will make the playoffs next year and I wouldn't be surprised to see them steamroll the piss out of the competition after opening the season very slow at 3 - 3.
Aaron Rodgers said post game "When I go back and think about it, I think at times we just weren't playing as aggressive as we usually are." and you damn well know Rodgers was just doing as coach told him to. Rodgers is very smart and very respected when it comes to procuring the game plan.
This cruise control Packers where they count their chickens before they hatch, will not happen again under Mike McCarthy.
