That is the conundrum, this defense does work (at least gets wins) against teams with immobile quarterbacks. But it also has failed spectacularly against good mobile quarterbacks and with teams that actually have the ability to game plan against it.
Defense is easy with LSU talent or with a guy named Suh on your team. However, it requires some thought and planning when that is not the case. We don't seem to be showing any willingness to adjust or get more aggressive with teams who have figured out how to exploit our scheme. Why didn't we blitz? How can we expect to maintain coverage for ten freakin seconds every down?
I think the D linemen we have could've gotten after Smith, especially with some blitz help, but their assignment was obviously to try to keep him in the pocket and wait to see if our DB's could play out of their minds. 600+ yards three times now. It will happen more if something doesn't change.
