Then, as KY said, you are not paying enough attention. They have been pulling Sitton a lot, Lang slightly less so. And its an old Power O I believe, with the Guard followed by Kuhn. Perhaps not versus the Boys, but at 4+ ypc, why would you change?
The Packers starting O line had a rookie center and a backup tackle in and the Seachickens are missing Mebane now, so quoting those rush statistics as argument for your analysis is useless.
