The Giants lost a cornerback on Monday when Coty Sensabaugh signed with the Steelers as a free agent, but they added one to their roster as well. The team announced that they have signed Valentino Blake to their 90-man roster in the same release that made their acquisition of quarterback Geno Smith official. Blake spent last season with the Titans and saw action in all 16 games. He played about a third of their defensive snaps and was a special teams fixture on the way to 42 tackles and five passes defensed.
