First & foremost, it would appear the Sharks are concentrating strictly on this year. Sure they would like to extend EK, but their attention is focused on winning it all in 18-19. They got him for basically nothing, so there won't be a huge meltdown at the end of the year if he walks on them.
Ideally, he would've preferred to stay in the east, but I guess he didn't have as much of a say as I thought he would. Frankly I'm shocked that any team traded for him without a new contract agreement in place, but with the robbery that took place, San Jose could afford to gamble for one season of Karlsson. With almost zero invested, I don't see the down side. They get a full season of him, and if they get lucky & he wants to stay, they really took Ottawa to the cleaners.
It's pretty obvious they didn't acquire him with the intention of trading him, so unless something really bizarre occurs & they're far out of playoff contention before the deadline, he's staying put all year.
Which begs the question; how did Ottawa only attach a 2nd rounder as compensation if EK resigns with San Jose? This really is the one of the most lopsided trades I've ever seen in sports. Feels like McPhee & a bunch of other GMs really blew it here.
Finally, when you mention Methot, I'm still baffled why we couldn't find a spot for him here. He's EXACTLY what the Knights need right about now. Maybe GM thought he couldn't skate well enough for Gallant's up-tempo style, but, IMO, he is the perfect stay at home partner for Theodore or Schmitty. But I digress...
