Ohhh I have a direct message for the Packers D as well, however, this being a family bar an all, I'll keep the vulgarities to myself.
I do not think talent is an issue on the Packers roster, offensively, defensively or even special teams. What I see on defense is players play out of position and failing to maintain their (perceived on my part) assignment.
Lack of rust is the biggest issue with the Packers defense. It is hard to beat the man in front of you when you don't trust the man next to you.
Do. Your. Job!
There is too much covering for deficiencies that lead to more of what they are intended to mitigate.
Do. Your. Job! And good things will happen.
Use man to man coverage and let Ha'Sean Clinton-Dix roam like a rover.
Each player on defense studies the player across from them and works hard to beat him. Learn tendencies, weaknesses, strengths and just beat him!
If that doesn't work, screw it, turn the Madden difficulty down to ROOKIE.
