Some of that is plausible, some is not.
I would not trade Hughes, nor do I think he is or ever will be a true top-pairing Dman. But he is a rare and valuable specialist. The Canucks have scarcely ever had a PP QB of his ability. In a league where skating ability is paramount, letting him go is a huge mistake. The problem with Hughes is that the Canucks are going to have to pay him as a top-pairing Dman to keep him here long-term. Jim (or his replacement) need to plan for that.
The other noteworthy part is Tryamkin. He's not going to leave Russia to come here for $2.25M/year. I don't think you'd get him for double that amount.
