I think most of us who are saying the Pack could lose tomorrow are saying so because of injuries. We just don't see Rodgers getting enough time to work his magic. That said, our defense will be on the field way too much, and they'll eventually wear down in the front seven.
It isn't gloom, saying this, it's being pragmatic, and figuring that if it happens, it's not going to derail the Packers opportunity to make the playoffs, or even win the big one. It's just a hiccup, and we get a chance to find out if we do have guys who can step up further down the road, giving the team even more confidence, even if they do lose tomorrow.
It's like one Patriot player commented after their loss. "Now we don't have to think about saying we can run the table."
There's something to that message. You learn from it, and move forward, with even more motivation than you had before.
