On the Cardinals people may flock to the "big" names, such as Dockett or Adrian Wilson. But, in my opinion, at this point in their careers neither are better than what we currently have.
Patrick Peterson really struggled at CB. Maybe he will be great in the future. But we didn't see it last season. Campbell is a talent. Though, there is no way he starts over J. Smith. Replacing McDonald would see more likely.
On the Rams? Anybody?
On the Seahawks? No linebackers. Browner may get the nod at CB. Possibly Earl Thomas at Safety.
Any other undeniable defensive starters in the NFCW? It's looking like slim pickings.
