The New York Giants added some defensive backs over night signing Seattle Seahawks cornerback Walter Thurmond III and Kansas City Chiefs safety Quintin Demps.

Morning. Giants busy overnight, agreeing on contracts with KR Quintin Demps and CB Walter Thurmond.

Demps doubles as a kick returner on special teams and can provide a spark for the Giants in that unit. That could be critical in a division that has seen the Philadelphia Eagles and the Washington Redskins get some big and critical signings. Pro Football Focus had Demps as one of the highest ranked returners last season.

Quintin Demps is signed by Giants to return kicks, but worth noting he started 6 games at safety in 2013. Depth there.

In more Giants related reaction, Quintin Demps was behind only Cordarelle Patterson in our kick returner rankings last year w/+7.1 grade.
