EAST RUTHERFORD, N.J. – Antrel Rolle has a Super Bowl ring. So does Prince Amukamara. And newcomer Walter Thurmond.

NFL veterans Dominique Rodgers-Cromartie, Zack Bowman, Stevie Brown, Quintin Demps and Trumaine McBride know the ropes.

Now, they all need to blend together in the New York Giants' secondary.

Thurmond, who left the Seahawks as a free agent just weeks after winning the championship — in the Giants' home stadium, no less — believes all of that NFL experience already has led to strong chemistry in the defensive backfield.
