Gregg Williams was apologetic and said he has made plenty of life changes at the press conference announcing his return to the NFL as senior assistant/defense with the Tennessee Titans on Thursday.

You learn an awful lot about yourself in the most difficult sorts of circumstances, some of the most stressful circumstances. You learn a lot about your family and friends, too,” Williams said Thursday via TitanInsider. “One of the things that I’ve always chosen to do is take any type of a situation and turn it into an opportunity to improve. One of the things that I really did this year was focus on as many self-improvement things as I could. It was a great study year. It was a great year to lose a lot of weight and get back healthy.

“It was a great year to travel. I’ve spoken all over the country. The media was unaware of all the different places I’ve been, really halfway around the world, some of the places I’ve been. I visited Thailand, worked with some impoverished villages, a lot of orphanages over there. ... I spoke to as many Pop Warner to junior high to high school to college football programs across the country, and I did that in a way that was trying not to focus any attention on me but on the game and would like to feel like, from a professional growth way, it was a good year that way. Anytime you’re as passionate and love something as much as I do this, you appreciate it even more when you come back.”

Titans coach Mike Munchak inquired with Commissioner Roger Goodell about the possibility of hiring Williams back in January and was given the green light to talk to him. From there, things fell into place and Williams was reinstated on Thursday, officially joining the Titans staff.

“I felt good about the talks with him, so I said the next step was to sit and talk with Gregg face-to-face and to get Ruston (Webster) involved in this, so I talked to him about the possibility and see if this made any sense,” Munchak said. “I thought let’s get together, so Gregg came to Nashville and we met the three of us for pretty much a full day and talked about a lot of topics. We covered a lot of things, from obviously football to everything that went on in New Orleans when he was there as a defensive coordinator. I think what came out of it was, I thought he was being very honest at what happened and I think he was being very humble by what he went through. I think he took responsibility for what he did wrong and the mistakes he made. I knew that he wanted to move forward."

Williams now moves forward in a new role and an old place where his pro career started, albeit in 1990 when the franchise was still the Houston Oilers.
