TLDR:
They have a lot of size on the DL and LB. They aren't fast.
He says to have any shot, they have to play a 5 man box with zone coverage to stop the run, and basically pray their way through the passing game. i.e. Dedicate DL and 2-3 LBs to stop the run, and the LBs can help in passing on pass plays.
He may be right, but that sounds like suicide. I don't think he mentioned our wide splits once, and that will prevent the LBs from helping in the run all that much. They'll need to basically declare for the run. And the zone folks will be schemed wide to prevent run help.
The more I hear, the more confident I become.
