Probably Lambos or O'Rourke and a draft pick at most.
The way we are going it would be a late 1st. Not very appealing for CBJ. I think MN has to look at what they want to accomplish with this trade. I am guessing that they want something that will help them this year in the playoffs, to persuade Kap when it comes to signing time that this team is a comer. They also don't want to be trading the future, if they can help it(Rossi, Yurov, Heidt).
I can see Granlund being a useful addition. While he can play C, he is also good on the wing, and his high offensive IQ would mesh well with Kap, Zucc, Boldy, and Rossi's game.
I think he could be had for a late 1st and a Milne/Bankier/Lambos type prospect. As an expiring contract, the $$ wouldn't be problem, but it would nice if they took Merrill back.
Getting a younger player or prospect like Jiricek is best left for the off season.
A guy like Batherson would be interesting, but i am pretty sure that the cost would be Rossi +. OTT might decide to go with the younger, cheaper guy with local ties if we add in a Lambos or 1st. I'm not sure how i feel about that, as i like Rossi, and OTT seems to be a bunch of losers. I think the idea is to add to what we have, not swap players. If that trade was done, then another player would have to be added.
Nyquist might be another option, and a very doable one, i think. He already knows the team, is a UFA to be, so $$ won't a problem, and NSH is clearly going downhill with the wind. I am guessing he will be the same cost as MiG?
