I think a MLB would do a lot to free up the interior rushers. We played incredibly conservative on the interior all season long. They were covering for the issues at middle linebacker by just stuffing up the middle. You didn't see many stunts or terribly complex movement up front.
We need to somehow turn up a strong middle linebacker at all costs. Trade the entire draft if you have to. Do whatever you have to do to find that guy. A superbowl literally depends on it.
