I think you're right and barring injury, we are only 2 linebackers and one free safety away from what might be the best defense in the NFL. But... I think we can get one of those linebackers in free agency and spend at least one more draft pick on a much needed help on the offensive line. There's too many players available at linebacker to not find a good deal. The oline is in serious need of repair. Rivera and Allen could give in at any moment. Even with a great defense, it would be foolish to not try and spend a high pick on the oline.
