I think this season has a better chance of resembling 2006 than being a down year

We are 1 legit CB away from having a super bowl contending team. If the Front Office really thinks this is a super bowl caliber team, then they absolutely have to get one via trade.
You know what makes a great CB, an AWESOME defensive line. If they put pressure on the QB from the start, hit 'em often, pressure him throughout and stop the run, then an average CB will look dominant and a dominant CB will take over the secondary.
