Reporting is suggesting that, in FA and the draft alike, this is a weak year for CBs and a lousy one for safeties. If that is correct, then it suggests that the Pats have to do some combination of: Beat the odds. Make do with what they have. Strengthen the pass rush to protect a questionable secondary. In particular, absent good luck, the safety corps will consist of: Chung JAGs Natural CBs That said, on nickel downs I don't see the harm in having the DB corps be: Chung 4 natural CBs And even in a base formation, I don't see why McCourty or Arrington couldn't play the safety role. What I do worry about is that safeties really need to avoid mental mistakes, and I'm not sure where that mental accuracy is supposed to come from in a new young guy, or in a moonlighting CB.
