I agree, though even a little retention likely opens up the market a bit.
Gotta imagine Keith would still drum up interest especially at his cap hit.
That being said, I fully expect all three of them to remain Hawks unless they request otherwise.
I don't think they will be moved too but you never know. There's still a slim chance it ever happens and just for fun I'm going to put up an offer from Montreal for Toews:
To Chicago:
Karl Alzner (4.65M for this year + 3 more)
Andrew Shaw (3.9M for this year + 3 more)
Ryan Poehling (Unsigned - 19 years old)
2019 Habs 1st round pick (unprotected)
2019 CLB 2nd round pick
Conditional 2020 Montreal 2nd round pick (Montreal advance to the 3rd round in either 2019 or 2020 - Otherwise it turns into a 2020 4th)
Michael McCarron (RFA at the end of the year)
To Montreal:
Jonathan Toews (10.5M - this year + 4 more)
Montreal money out: 8.55M
Chicago money out: 10.5M
The two key pieces for Chicago are Poehling and Montreal's 1st. Poehling is already in his D+2 so he's further down on his development and is considered to be a lock to become an NHL C - Probably a middle 6 two-way C. With Chicago 2019 1st (and the likelihood that they draft a top C) and Poehling, Chicago will be well taken care of down the middle. The extra 1st, mostly a mid 1st round pick, let me pick another solid asset.
I included Alzner and Shaw for money reasons as Montreal can't take on 10.5M without something going back. Shaw can be sold later on for value as well.
