Quoting: Korax
You can think about mony during the offseason for Landeskog imo. And for Olofsson, it is just a contingency just in case, just like Parise is also.
Trading Mittestadt is very low on my priority list.
Getting a LHD (Bowen Byram) when Buffalo has Dahlin, Power, Samuelson and Ryan Johnson who are all 23 yo or younger is not a top priority.
Even lower among Buffalo needs is a 22 yo RW who has zero NHL experience.
With all that said, as much as I like Casey adding defensemen (RHD would be better) and first round picks gets my interest.
Replace Beaucage with Johansen would actually be more palatable to me.
Buffalo is playing Bryson at LHD so Byram would replace him, and Johansen would take Casey's spot as 3rd line center at for the next two years.
It will not make Buffalo a playoff team as this season has not gone well and maybe a change is needed.
Maybe the first round pick and other assets would interest another team to trade a young RHD to Buffalo.
