They signed former Raven FS Will Demps. See story here: http://sportsoutlaw.com/nflnews/

The Giants definately didnt waste anytime going after people, that seemed to be how most teams attacked free agency this year.

THey also signed CB McQuarters which should provide some nice depth.

Demps, McQuarters and Madison are all GOOD signings, just not GREAT signings. Do they increase the position they were in after losing Will-squared...yes. It'll be nice to have someone that can actually play besides Gibril Wilson. But none of these signings are blockbusters or anything beyond mending a hole...they still need quality talent in the secondary.
