So I guess the Packers aren't an elite defense?

They played a very bad game, kind of reminded me of their D in the beginning of the year. Bad games happen, but their lack of depth at the CB position killed them in this one. Their scheme was good, they stopped the run as they always do, but their backup CB's stunk it up bad. It happens. The Steelers took advantage of it as they should have done and played well. Congrats to them.
