Perhaps they are not the team we thought they were, and the problems were more than just Jordy being out last year.
I think the fact that Nelson missed all of last year an so far has looked like a shell of his former self is a big part of it.
Nelson is one of the best deep ball receivers in NFL history and for the past 5 years the Packers have relied on Nelson to blow the top off of the defense -- opening everything up underneath for the Randall Cobb, Greg Jennings, Jermichael Finley's, etc of the world.
Now Nelson is averaging 11 yards a catch and at age 31, recovering from a blown ACL, there is a good chance he'll never be that guy again.
Honestly, people talk about how good the Packers WR are -- I just don't see it anymore with the current group of Nelson, Cobb, and Adams (who looks very average to me). Their TEs are nobodies and they have a plodding running game.
The Packer's down the field explosiveness is long gone and isn't coming back this season.
Beyond all that Rodgers hasn't been himself and now, 16 games into this stretch of average play, you have to wonder if this is more than a 'funk'... ie his skills are diminishing as he approaches age 33.
What they do have is a top notch OL and a decent running game.
It's a very different team.
