On the defensive side of the ball, yes, they have gotten better, most notably in the secondary. They were able to add veteran safety Adrian Wilson, re-sign cornerbacks Aqib Talib and Kyle Arrington and jettison safety Patrick Chung. If Alfonzo Dennard is able to return without missing a beat, all of these moves will help stabilize the New England secondary, a group that made tremendous strides down the stretch in 2012.
