Former Saints defensive coordinator Gregg Williams returns to the Superdome Sunday, as he performs the same duties for the Los Angeles Rams.

Williams was the mastermind of a Saints defensive turnaround in 2009, that helped the club to its only Super Bowl title. He departed after the 2011 season. Williams and Saints head coach Sean Payton were both suspended by the NFL for their alleged roles in the Saints alleged bounty scandal.

Saints safety Roman Harper, said he still keeps in touch with Williams, and says he loved playing for Williams in New Orleans.
