They traded a 2017 3rd for a 2017 1st, what's not to like?
But seriously, I like Samorukov but it never appeared that management did so I look at it this way, there's a better chance that Kostin finds a niche on the Oilers (albeit slim chance) than Samorukov who was never getting a chance here so it's fine from that perspective. Ultimately, it'll probably end up being a nothing trade.
On another note, so the Oilers are likely to start the season over the cap it seems. How is that going to work unless they run with a 20-21 man roster.
