It would be awesome to get a Safety of Eric Berry's quality. However, to pry away from KC, you'd be mortgaging the future and giving up too much. Rarely do big FA signings actually turn out better for the team paying thru the nose (see Williams, Mario). The best way is thru the draft. Get some quality players that are hungry, let them prove themselves and not pay a ton. This is how the Patriots do it and other successful, perennial playoff teams. Drafting 29th, 30th, 32nd hasn't stopped them from continue to succeed in finding players.
