Quoting: Wilbur
They could, but Johnsson was very underwhelming and the slightly cheaper Kassian likely has a lot of appeal given the lack of physical players on the team. As well, Boqvist is not having the expected impact and the much bigger Maltsev is eating his lunch in the CF department.
Koskinen is better and has much more experience than previous back-ups in New Jersey. He does very well with a smaller workload, and would be an ideal fit there.
Look m8, Johnsson, who is primed to have a bounceback for next season (either in Jersey or Seattle), him being cheaper than Kassian has no bearing on NJD whatsoever, they have the most cap space in the NHL. As for EDM, you guys are pretty screwed in regards to the cap with the Kassian and Koskinen being large culprits in said screwery. Why do you think NJD would allow Holland to dump cap like that for free? Larsson, RNH and Barrie are all UFA, where do you see Holland having any leverage in this situation?
There are gonna be many suitable goalies to target free agency (Ullmark, Driedger, Halak to name a few) and better goalies that are under contract to poach ahead of expansion draft (like Vanecek), there's no need to take on that Koskinen contract whatsoever.
Also, Boqvist could very well establish himself as the 3C in Jersey for the next season, he has that potential.
All in all, this is a terrible trade proposal, not gonna happen.
