Sorry if this was already posted. Didn't read the whole thread:
Since we're stuck with Rex for now, it seems to me the only way for him to install his defense, which he seems to want to do, is to get a legit NT. In his scheme the D line is predicated on that. Whether in the draft or FA this is what he needs to do. Other posters have more info than me about what's actually out there. This way Dareus and K.W., if he stays can move to DE. Hughes can then be an OLB in the scheme. Fortunately, he may already have the CBs for his scheme.
