You're right the defense and special teams should be improved over last season. I don't expect them to win 13 games as long as the offensive line doesn't dramatically improve in pass protection compared to the first two games though.
That's about right. It is hard to Win in this league, but we don't need to Win 13 games to get to the Superbowl. We just need to gel at the right time (see 2010)
Agreed about the IR situation. How the Packers are handling not putting him on IR tells me 1 of 2 things. Either 1. they really DO think he's close to returning to the field and have full faith he'll play soon or 2. they grossly mismanaged the roster situation by taking away a spot from someone that actually could help the team if they had doubts he'd play in the first 4 weeks.
It's a guessing game from week to week but he did practice several times last week.
I'll be watching to see what he does this week, if he does not practice? that's a bad sign (regressing)
If he practices every other day again? That's a relatively good sign (stable)
If he practices at a more consistent basis than last week, I expect he'll play in the next couple of weeks (improving)
