Like a rock ‘n’ roll group getting back together for a reunion tour, those who know Jeff Fisher said he wanted to “put the band back together” for one last run at the Lombardi Trophy when hired by the Rams in 2012. Fisher brought trusted aides Dave McGinnis, Chuck Cecil and Gregg Williams with him, coaches who had enjoyed much success working for Fisher over the years in Tennessee. However, Williams didn’t last long thanks to the “Bountygate” scandal in 2012. But after Williams’ year-long suspension by the NFL and then a season as a senior assistant with the Titans, he finally is reunited with Fisher. The band is back together. “It’d be no greater thing for me than to say this is my last move,” Williams, 55, said Thursday during his introductory news conference as Rams defensive coordinator. “I’ve had an opportunity to work and coach at a lot of good organizations in the National Football League, and I really look forward to working for this organization right here. And potentially retire right here and win an awful lot of games.” Fisher and Williams won a lot of games the last time they worked together. In the four seasons that Williams was Fisher’s defensive coordinator — from 1997 through 2000 — Tennessee went 42-22, won a division title and played in Super Bowl XXXIV against coach Dick Vermeil’s Rams. That level of success was more impressive when you consider that the first two seasons of that mini-run — ’97 and ’98 — Fisher’s Tennessee team was in the midst of arguably the toughest franchise relocation, from Houston, in NFL history. In 1997, Tennessee played in Memphis, which just a few years earlier had fallen short in a lengthy and costly bid to land an expansion team. Still smarting from that civic setback, the good citizens of Memphis didn’t exactly embrace the Oilers/Titans. In ’98, the Titans finally made it Nashville but played at Vanderbilt University. With Williams orchestrating a snarling, aggressive defense, the Titans posted back-to-back 13-3 season in 1999 and 2000. That ’00 squad finished No. 1 overall in total defense and No. 2 in scoring defense.
