Gregg Williams Joining Jeff Fisher's Staff with St. Louis Rams

It didn't take long for Gregg Williams to ditch the New Orleans Saints' shambolic defense for a new pet project.

According to the NFL Network, Williams has signed on to serve as the defensive coordinator on Jeff Fisher's staff with the St. Louis Rams. Williams coached under Fisher with the Tennessee Titans from 1997 until 2000, before taking over as the head coach of the Buffalo Bills in 2001.

Williams spent three seasons in New Orleans, stewarding the famed "Who Dat?" defense that helped carry Sean Payton's Saints to their first Super Bowl title in franchise history two years ago. Williams' contract expired at the end of the season and he was unlikely to return to the Big Easy after overseeing a unit that plummeted from fourth in the NFL in total defense in 2010 to 24th in that category this past season.

The 53-year-old defensive guru will have yet another reclamation project on his hands in the Gateway City with the league's 22nd-ranked defense, 31st against the run.

Known around football for his creative and relentless blitz packages, Williams figures to go after opposing quarterbacks as hard as ever, with Chris Long, James Hall and rookie Robert Quinn comprising the Rams' rising pass rush.

Williams will be joined on the sidelines in St. Louis by former New York Jets offensive coordinator Brian Schottenheimer, who will fulfill the same duties under Fisher.

As for finding Williams' replacement in New Orleans, the Saints are said to be after former Rams head coach Steve Spagnuolo and Miami Dolphins assistant Mike Nolan to fill their vacancy at defensive coordinator, per ESPN.
