Not sure he would choose us. But if we acquire him while him having two RFA-years, getting him under a long-term contract might be a lot easier.
And if and when Murray wants to be as good as possible next season, getting an elite fourth-line-center fulfills your short-term goals as well. I think Krüger is a prime example of "cap casualty" - he's a quality piece, but a team in as bad cap crunch as Chicago is, might not be able to offer him a contract close to 2 millions, and we have the assets to overpay for a fourth-liner trade and contract wise. I think that if you pack enough non-first round picks, Chicago really have to listen.
