This has been a Blitz that seem to confuse the OL especially the Tackles who for some reason block down instead of to the outside. I know the Defenders gets paid too but this is a Blitz that just creates confusion with most Blocking Schemes, which i bet is by design. I think the empty Backfield is not a good formation against this because the QB becomes a sitting duck if the Free blitzer gets through. A RB or 3rd down Back should be in at all times to guard against this. Matt Cassel took some shots completing plays that defeated this blitz. But do we want Cassel to take those kind of shots vs Pittsburgh? I am sure Pittsburgh will see the tapes on how Miami came close a couple of times with that Blitz scheme and Pitt has a more sophisticated D. Food for thought.
