You are really only arguing semantics here, the situations are very similar and can/should be handled as such.
Do you think the Canucks handled Tryamkin well as an asset?
It's not semantics. It's an entirely different situation and timeline where one becomes a UFA in a matter of months while the other has a full year left. If I was advising a college UFA I'm telling him that he might as well wait to become a UFA and control his destiny. If I was advising Tryamkin, I'm telling him to sign a 1 year deal and become a UFA next year if he wants to play in the NHL and maximize his earnings. From an NHL team's perspective, if you can't sign a NCAA player who finished his senior year in March, he's not signing with the team. Tryamkin's season ended after the NHL trade deadline.
How often do you see Russian players in comparable situations sign a KHL contract in April/May? Usually players who tell their teams they are going to the NHL go to the NHL unless there are no offers. Nesterov signed in October. Gusev was traded in the offseason. Datsyuk decided to go back to the KHL in July.
How far apart do you think the Canucks were with Tryamkin? Reportedly, Tryamkin wanted to come back they were discussing 1-2 year terms and the Canucks had offered more than $1M. So if I was Benning and I offered him more than $1M, I would think there is a pretty good chance of him signing and it was only a matter of time that the deal got done.
