That sacrifice comes with letting DeSmith, Cole and potentially Blueger walk while trading Mikheyev for nothing. I'd prefer keeping Blueger if possible but we have an alternative with him in Suter. We don't with Soucy. Sure, if you find one, then it opens the door but I still don't think it's something they're consider.
You also have to consider Juulsen will get a good look next season. Better to pair him with a defensively responsible player like Soucy than a cheap journeyman. Even getting Tanev doesn't necessarily make Soucy expendable because they play different positions.
It really all boils down to the demands our UFAs have. I love what Zadorov's brought but money truck jokes aside, he's realistically a 5M-ish player. If he wants say, 6x6, that's just too rich. I worry it'll become Myers 2.0 all over again. Same with Hronek and 8M+. If he sticks to that, then we seriously consider moving him and fitting everyone else in isn't an issue.
