Most of their salaries are way too high for any contenders to take on.
Horvat, Domi, Gavrikov, and Ghost can all be retained down to affordable cap hits. But as @Point21 says above, teams with cap space that aren't moving out a ton of guys are gonna be in high demand this year as 3rd party retainers. Sure hope that Lou realizes he's allowed to do that this year!
I'll bet that Nyquist, Gavrikov and Gostisbehere all get traded. I have no idea where.
Gavrikov I could see being traded to Edmonton. If the Rangers don't trade for Kane I could see them adding Nyquist to add more depth. Gostisbehere I have no idea.
