EAST RUTHERFORD, N.J. -- Less than two days after Steve Spagnuolo left to become coach of the St. Louis Rams, Tom Coughlin promoted linebackers coach Bill Sheridan to replace him as the New York Giants' defensive coordinator.

"Bill is a very good football coach," Coughlin said Monday. "He does an excellent job of teaching, of reinforcing what we aspire to be with our defensive team. He's coached our linebackers, he's given a big assist to Steve in all that he has done."

Coughlin interviewed Sheridan and secondary coach Peter Giunta for the coordinator's job Sunday. Giunta was the Rams' defensive coordinator when they won the 2000 Super Bowl.

The Giants played an aggressive blitzing defense in Spagnuolo's two years as defensive coordinator, and Sheridan said that he will keep the system, although he will make some modifications.
