On a high-flying offensive unit, Coburn was a steady defensive influence last season. He finished with 23 points, his highest output since 2011-12 with the Philadelphia Flyers.
Coburn, 34, is coming off a three-year, $11 million contract that he signed with Tampa Bay.
After acquiring defenseman Jan Rutta from Chicago, the Lightning extended the defenseman for one year. His presence led to Coburn being a healthy scratch for two of Tampa Bay's four playoff games this past season.
