Here our options, essentially:
1) Trade Murray by parting with some sort of sweetener
2) Trade another large contract like, say, Nylander
3) Treliving already knows that Murrary is unfit to play, so they Robidas Island him and bank on LTIR and a couple of small roster movements to squeak by
4) Buyout Murray. Now, we passed on the initial buyout window, so the only way to do this is by unlocking the second buyout window by entering into salary arbitration with another player on the team. The only player eligible is Samsonov. Also, the team passed on the Club Elected arbitration window, so it would have to be Player Elected. So technically there is a non-zero chance that Treliving's plan is to refuse to negotiate in good faith with Samsonov and his agent and hope they choose to go to arbitration and actually go through with the hearing, so that they can buy out Samsonov's own goaltending partner
