Another option is trading Swayman. He's younger, controllable and projectable to an acquiring team. The closest comp I can think of is Jake Oettinger who signed a 3-year, $4 million AAV extension prior to this season. At the time, Oettinger had 77 NHL games and a .912 save percentage. Swayman is 89 games .920 save percentage and is arbitration eligible so my guess is he comes in north of Oettinger.
The more I think about it, the more I think a goalie has to go. I'm not sure they can commit ~$10+ million in cap space to the position. IMO, pick one and move the other. From an on ice standpoint you can only play one at a time anyways. It's nice having a good backup but they've had some success in the free agent market finding these guys (Halak) plus they have some depth in the prospect pool (Bussi, Keyser, Svedeback).
The other notable RFA is interesting too, Frederic. The qualifying offer is $1.15 million. There's been some chatter that ne could be a non-QO candidate. I would think he has enough trade value that they wouldn't have to go that route, but we'll see.
