I would actually not be surprised if he has somekind of a gentlemans' agreement with the Flames about this. He's on a 1-way deal and would most probably be a healthy scratch for most of the season so now he gets to play in a top league and the Flames get an extra contract + some capspace (I think?).
IIRC the KHL is the only major Euro league that doesn't have a transfer agreement with the NHL.
Well, they don't have a binding agreement, more of one of the handshake variety. But for the most part, since Radulov went to the KHL, players haven't signed in the opposing league if they have a contract with a team in their current league.
Wilson was a decent depth option to have around though, and makes for a nice fill-in if two of Gio/Wideman/Brodie/Smith were injured at once, for example.
Don't really like this, but I'm also indifferent to it. Smith is clearly ahead of him and we already have Babchuk and Smith as extra dman. It would of been nice to keep him for depth, but being that he was on a 1-way he probably would of been waived to start the season.
The only thing I absolutely hate about this, is was more than likely Abby's MVP last year. And while he probably would never see the light of the NHL with the depth chart in front of him... It really hurts the Abby team, hopefully someone like Wotherspoon can step up maybe... Or Lamb, because that's a ton of points and minutes to cover from the backend.
