the Packers went 15-1 last year with a shyt defense.
When you have a QB like Rodgers and weapons who can basically put the ball into the endzone any time he wants...it outweighs anything a defense can do.
That's the thing, you can win all the games you want with a trash defense in the regular season, but in the post season you have to face teams with good O and a good D.
Packers had a very fruity schedule if we don't recall, I dont think they played a top 5 defense all season.
Saints - bad D
Panthers - terrible D
Bears - good d, but not great
Broncos - good d, but were awful at this point in the year
Falcons - okay defense at best
Rams - terrible team
Vikings - terrible team
Chargers - terrible D
Vikings - terrible team
Bucs - bad team
Lions - good team, defense was swiss cheese though
Giants - good team, at this point D was still suspect
Raiders - decent team
Chiefs - bad team, which they lost to
bears- same as before, no Cutler though now
Lions - bad d, backups beat them
You see why their 15-1 wasn't that impressive and why they were able to cost with no D, once they played teams that did both well in the playoffs, they folded.
