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.
