The Tampa Bay Lightning has signed defenseman John Carlson to a two-year deal worth $17 million, which carries an average annual value of $8.5 million, per the team.
Carlson is expected to be a big boost to the Lightning’s blue line. The 36-year-old blueliner is coming off an impressive season with the Washington Capitals and Anaheim Ducks and should play a top-four role with the Lightning.
How Carlson Did in 2025-26
The 2025-26 season was the end of an era for Carlson and the Capitals. After 17 seasons with the Capitals – his only club – Carlson was traded to Anaheim for a first-round draft pick in 2026 and a third-round draft pick in 2027.
Carlson was excellent with the Capitals, scoring 10 goals and chipping in 46 points in 55 games. After he was traded, he fit in well with the offensively dynamic Ducks, scoring four goals and adding 10 assists in just 16 games.

Despite not having a goal in the playoffs, he added six assists and served as one of the team’s top defensemen. His veteran presence was definitely welcome on one of the youngest, most dynamic teams in the league.
What Carlson Brings to the Table
Despite being 36 years old, Carlson is still capable of playing top-pairing minutes for virtually any team in the league. He can also man the top power-play unit, where his heavy shot and deft passing skills make him an asset.
Carlson is still also capable of playing big minutes at his age, playing more than 24 minutes per night for the Ducks, right around his career average with the Capitals. He may not be a defensive stalwart, but he more than holds his own and offsets mistakes with his prowess at the offensive end of the ice.
How Carlson Fits with the Lightning
Carlson immediately becomes the power-play quarterback and a top four minutes-eater. With the right partner, he can focus on moving the puck up the ice; his excellent passing and smooth skating are part of the package.
As a veteran, he brings calmness and poise to the table that you don’t get with other defensemen. The Lightning will benefit from the consistency that his performance brings, not to mention his reliability and availability, having played the majority of his team’s games over the past three seasons. After losing Darren Raddysh, getting Carlson was needed for the Lightning to keep their blue line competitive.
