"Gregg Williams, whose defensive revival helped lift the New Orleans Saints to their first Super Bowl championship two years ago, is leaving to become the defensive coordinator of the St. Louis Rams, according to various reports.

The move has been anticipated for several days, since Williams' contract was set to expire with the Saints and his close friend Jeff Fisher was hired as the Rams' head coach. The NFL Network and St. Louis Dispatch reported Monday that he had officially agreed to the move."
