It's the preseason, a bit early to be talking about stuff like this IMO.
That being said, I think the Packers defense was highly underrated last season and I wonder if we would have been top 10 in most categories, top 5 in some had the offense had its usual output and the punting not sucked. They got put into some reliably horrible spots and did a damnned good job. If they can cut even one boneheaded blown play per game and the offense can go back to what we expect of it, I wouldn't be shocked if we were a solid top 10.
