Justin Braun, Philadelphia Flyers
Braun joined the New York Rangers prior to their run to the Eastern Conference Final last season and could help a contender again. The 36-year-old stay-at-home defenseman is a pending UFA.
Matt Dumba, Minnesota Wild
The 28-year-old has 13 points, his fewest in his nine full NHL seasons, and has been a healthy scratch on several occasions this season. Dumba, who is a pending UFA, can provide physicality and grit.
Erik Karlsson, San Jose Sharks
Karlsson is closing in on what would be his best NHL season. He leads all defensemen in goals, assists and points, and the Sharks may have to take on some of his salary cap charge ($11.5 million average annual value for the next four seasons after this one). The 32-year-old would make any team better, but how much are teams willing to give up for his services? So far, the Sharks have not asked Karlsson to waive his no-movement clause.
John Klingberg, Anaheim Ducks
Klingberg was not moved at the deadline last season and signed a one-year contract with the Ducks in the offseason. With Anaheim out of the playoff mix, the 30-year-old could be on the move again. Klingberg averages more than 20 minutes of ice time per game and can play in all situations.
