For example, if you think McCarthy is the problem, do you fire him? If so, who do you want to replace him that you think will be a difference maker for this team?
Let's not just say "Rodgers needs to play better." That's a no brainer, but unfortunately something only Rodgers can fix.
For me:
Offensively:
1. If McCarthy is to stay, they have to run more 4 and 5 WR sets. They actually ran a hurry up 5 WR set towards the end of the game that appeared to be working, only until Rodgers fumbled the ball on a designed (maybe?) QB sneak. I don't think I've seen the Packers run a designed QB sneak in my entire lifetime of watching them, but hey, why not start now

2. Quick Plays: After 5 games, I think it's fair to say our offensive line is the strongest part of this team. The line gives Rodgers so much time (but unfortunately we can't seem to get anyone open down the field?). I'd like to see us run a few plays with Lacy or Mont in the backfield originally set for pass protection then run out on a quick pass for a decent gain. If our receivers can't get open on perfect pass protection, then adjust the game plan and make them respect the short dump passes. Eventually defenses will have to start playing the short dump offs and it should open up play down the field. Seems like we just keep trying the same things over and over again, hoping it will work only to build this false sense of reality that our offense is a "big play" offense.
Defensively:
1. I'm not as upset about Elliot going for 150+ yesterday. In reality, their running offense is just better than our run defense, and no one should be surprised there. I do still think the run defense is legit and will continue to play at a high level. The problem I have with our defense overall is the lack of aggression they play with on a consistent level. There are two guys that always appear to have their motor running the entire game and that's Nick Perry and Mike Daniels (I'll throw Clay in there as well because he usually brings a high motor but just isn't performing on a stats level so far). The rest of our team appears to show up for a few plays then kinda disappear. If you watch top tier defenses play, they always swarm the ball, no matter where it is. If the opponent catches the ball in the middle of the field, it's almost assumed they are going to rip off a decent gain. I always get frustrated with Seattle (mainly because they've had the Packers number for a while), but if you watch film from when their defense was hands down the best in the league, it always looked like they played with 13 or 14 guys because every single man on the field played with lights out aggression. Despite a great run defense up to this point, I just don't see that type of play style coming from Green Bay.
2. I didn't play football growing up, so my understanding of schemes and personal comes solely from me watching the game for so long, but can someone tell me why we don't jam receivers at the line? I'm specifically talking about Randall. It seems like every time he's on the field, he plays 10 yards off the line, let's his receiver get a full head of steam then get's beat. Why not jam receivers at the line and try to disrupt their rhythm?
