Great defences do win superbowls, just a pity our brain trust saw the wisdom of trying to do it on offence last year, and what did it get us 8/8. What if we spent resources getting a stud linebacker in free agency not a running back in McCoy, another dominant stud in the secondary not Charles Clay, another dominant linesman not Percy Harvin. My opinion is that we would be no worse than 8/8, but would have had the nucleus of a championship calibre defense.
