Williams has bounced around since his four-year Broncos tenure concluded after the 2016 season. The former first-round pick played for the Titans in 2017 and split time with the Lions and Dolphins last season.
The 30-year-old defender played 376 snaps in 2018, starting four games with the Lions and playing 14 total in Detroit and Miami. His last full-season starter role came with the Broncos in 2016. The Titans used Williams as an 11-game starter in their 3-4 defense.
Williams marks the second veteran inside defender the Saints moved on from today. They also released Ziggy Hood, whom they signed just ahead of training camp. Hood was last a full-time player with the 2017 Redskins, with whom he was a 13-game starter.
