Packer D is suspect, they let the Vikings move at will when they went prevent late. But word from Packer beat writer Demovsky is Rodgers looked better in camp than he had in many years and despite what he said publically the Love pick pissed him off.
Clearly he was motivated and super sharp. How long that continues is hard to say because historically it doesn't take much to tilt him into pouty mode where he loses interest but I would assume he'll look good for at least the first few.
Regardless I generally won't go against the Pack in Lambeau because of the constant officiating shenanigans on their behalf--last years Lions game being one of many examples.
