The struggling Giants have demoted longtime starting defensive end Osi Umenyiora to the second team in practice. New York demoted tackle Fred Robbins as well. The Giants have lost five of their last six games and are heading into a critical game against the Cowboys this weekend. "We will play everybody," coach Tom Coughlin said. "We will get everybody involved. We are trying to do the best we can in maneuvering our personnel according to our team. We preach team defense, so we are going to try to get other guys involved as much as we can and see if we can't solve some issues."
