Well, if they think they could re-sign him, he might be worth the risk. Of course, his asking price is probably too much for the Blackhawks. Still, in terms of roster-level assets, the following players could be of interest:
Andrew Shaw (24 year-old RW with 30 points so far this season) - They probably won't be able to re-sign him to an affordable contract since they have a number of other RFAs that will have more affordable contracts. He's getting 2 million now, but we could possibly combine him with another player to keep CHI from going over the cap too much. Boedker could help them this season, and that would be 4-5 million they could spend on their RFAs once Boedker went UFA
Bickell (LW) - while not too tempting to add, he might be willing to waive his NTC (I'm sure we aren't on his list of 8 possible teams he'd be willing to be traded to) to be playing back in the NHL. His contract is expensive, but we could stomach it for next season. Still, he would be a bit pricey for a 3rd/4th line forward, but we could possibly get a decent deal in other assets by agreeing to take him.
In terms of prospects:
McNeill (C/RW)- Two-way player that could make it to the top 6 (eventually)
Kyle Baun (RW) - Kind of a gamble, but could develop into a solid 3rd/4th liner
So, I don't know, Boedker (3.75 million UFA), Stone (1.15 million RFA), and a pick for Bickell (4-4.5 million), Shaw (2 million RFA), and McNeill (.86 million RFA)?
