Lewis didn't take a paycut with the restructuring, while the team managed to find $1.2 million in salary cap savings in 2014 and $1 million in savings for 2015.
Lewis registered 47 tackles, on forced fumble and four interceptions in his first season with the Saints in 2013.
Saints lock up Jairus Byrd long term
by Chris Towers | CBSSports.com (3/11/14) Though they have little room under the cap, the Saints somehow managed to find room for one of the best free agent defenders available. A few hours after free agency opened Tuesday, the team announced the signing of safety Jairus Byrd, the financial terms of which are not yet known.
Byrd has made the Pro Bowl three times in his five-year career, and is coming off a four-interception, 48-tackle season despite playing just 11 games for the Bills last season.
