Komarov you keep because he's signed long term... the others were brought in on 1 year deals for a few reasons, one of which being, if we're out of the playoffs, they are cheap and pending UFA's, thus major deadline trade bait, and that is how they should be used.
Next year a new slew of cheap and almost identical players will be available once more ...this is how you work a team, if you are filling the bottom 6 with UFA's rather than your home grown youth!! ...we didnt do it properly with Macarthur, and Raymond, and got back squat, and it's not like either is setting the world on fire since... they both should have been dealt.
sign em cheap and short, build up some value, trade them off for futures, repeat.
shame he's played really poorly, as Booth was another in the same boat, but likely nobody will want him, save for a really late pick, or a low end or real longshot prospect.
