I think you guys are taking way too much out of preseason regarding the run defense and pass rush. Obviously record means nothing, but I think too much is made about the performance of the starters as well.
Until I see these problems appear in games that actually matter (and with everyone healthy, something that we haven't had all preseason) I'm not going to get bent out of shape.
Of course it would be nice to have Williams back now, but at the time everybody was praising Thompson for getting good value for a player that didn't even want to stay here. Add in our depth at DT (at the time, obviously) and it would have been a mistake to pass on that trade.
Regarding Brohm, of course he's going to look lost out there. Even Peyton Manning (one of the most NFL ready quarterbacks to ever come out) had a terrible first season. The adjustment period for quarterbacks and linemen is much longer than it is for a lot of the skill positions.
The season is lost if Rodgers is out and getting the young QB's some experience is much more important than posting a better record, IMO. This is a team with Super Bowl hopes, not a team trying to post a record above .500, and that's all bringing a veteran in will accomplish.
