If you have time, go watch just the highlights from the Crosby/BH game, and then any footage from the BH/PNG game. The Crosby D line blew past the BH line like they weren't there at all. The Crosby D line players don't appear to be particularly large. I don't know what scheme Crosby was running, or how many down linemen. But then look at the PNG game -- almost zero penetration all night. Even though the BH O line is big, there is a way to beat them and it doesn't require being as big. PNG is getting outskilled on D line, not just outmuscled, whereas the Crosby D line outplayed, instead of outmuscling, the BH line.
